Depending on the season, sporadic showers of rain are besides common. Make convey a camera, for the position is fabulous and you will non be disappointed. Nuuanu Pali is surrounded by dense forest heavy with wet. As you travel up Pali Highway, the houses begin to thin and the verdure begins to take over. During the winter and spring there are many waterfalls to be seen in the mountains. The trees, covered with moss and green writhing vines, block out the Sun and civilisation. The workss and vines seem to hold taken over everything except the asphalt route being driven on. All of a sudden, the forest terminals and a little unfastened parking batch appears. The sentinel is at the terminal of a paved paseo. On the sides of the paseo are a twosome of sellers. One seller sells Jerseies and custodies out booklets which educate people about the issue of Hawaiian Sovereignty. The other seller sells Polynesian humanistic disciplines and trades. As you stand at the sentinel, expression at the knife-edged ridges to your left and right. These cragged weaponries that embrace the win dward side as far north as Kualoa and as far south as Waimanalo are mere leftovers of Koolau mountain, they are landward wall of what once was a monolithic vent. Time and ocean tides have eroded and collapsed the offshore side of the vent. From the sentinel, many towns and topographic points of involvement can be seen. To the left is Kahaluu and the new H-3 expressway. Straight in front is Kaneohe and Kaneohe Bay. Olomana and Kailua are to the right. You can besides see Kaneohe Marine Corps Air Station, the Koolau and Pali golf classs, and Kapaa Quarry. The Koolau Mountains are amazing, olympian, and breathtaking. The blues of the ocean and sky blend together, doing it hard to state where the Earth ends and where the sky begins. Sometimes, the clouds and mist bead depression over the mountains and sheets of rain can be seen falling over the land and sea. Double and ternary rainbows are besides a familiar sight. The cold air current invariably blows and brings the aroma of rain, ferns, and moist Earth mixed together. Standing at that place, at the border of the drop, watching land, sea and sky semen together and feeling and hearing the tanning wind all about, it is easy to be transported back to a clip before concrete, cars, and pollution. More than 200 old ages ago, a great warrior head from the island of Hawaii named Kamehameha envisioned unifying all the Hawaiian islands. Many heads, including High Chief Kalanikupule from the island of Oahu did non portion in Kamehameha # 8217 ; s dream and decided to dispute him. In 1795, 1000s of Kamehameha # 8217 ; s warriors drove Kalanikupule and his ground forces up to Nuuanu Pali where many fell or fought to their deceases. Subsequently, in the early 1800s, the kamaaina would track the deadly Nuuanu Pali with kids, nutrient, and supplies tied to their dorsums. In 1897, a main road was built and during the building, workers found about 800 skulls and other castanetss at the underside of the drop # 8211 ; remains of the warriors who were defeated by Kamehameha. Many more betterments were made to the main road and now the old route is a boosting trail which branches off from the sentinel point.

Melting Ice Science Experiment

Melting Ice Science Experiment This is a fun, non-toxic project for kids of all ages. All you need is ice, salt, and food coloring. Materials You can use any type of salt for this project. Coarse salt, such as rock salt or sea salt, works great. Table salt is fine. Also, you could use other types of salt besides sodium chloride (NaCl). For example, Epsom salts are a good choice. You dont have to color the project, but its a lot of fun to use food coloring, water colors, or any water-based paint. You can use liquids or powders, whichever you have handy. Materials watersaltfood coloring (or watercolors or tempera paints) What To Do Make ice. You can use ice cubes for this project, but its nice to have larger pieces of ice for your experiment. Freeze water in shallow plastic containers such as disposable storage containers for sandwiches or leftovers. Only fill the containers part way to make relatively thin pieces of ice. The salt can melt holes all the way through thin pieces, making interesting ice tunnels.Keep the ice in the freezer until you are ready to experiment, then remove the blocks of ice and place them on a cookie sheet or in a shallow pan. If the ice doesnt want to come out, ts easy to remove ice from containers by running warm water around the bottom of the dish. Place the pieces of ice in a large pan or a cookie sheet. The ice will melt, so this keeps the project contained.Sprinkle salt onto the ice or make little salt piles on top of the pieces. Experiment!Dot the surface with coloring. The coloring doesnt color the frozen ice, but it follows the melting pattern. Youll be able to see channels, h oles, and tunnels in the ice, plus it looks pretty. You can add more salt and coloring, or not. Explore however you like. Clean Up This is a messy project. You can perform it outdoors or in a kitchen or bathroom. The coloring will stain hands, clothes, and surfaces. You can remove coloring from counters using a cleaner with bleach. How It Works Very young kids will like to explore and may not care too much about the science, but you can discuss erosion and the shapes formed by running water. The salt lowers the freezing point of water through a process called freezing point depression. The ice starts to melt, making liquid water. Salt dissolves in the water, adding ions that increase the temperature at which the water could re-freeze. As the ice melts, energy is drawn from the water, making it colder. Salt is used in ice cream makers for this reason. It makes the ice cream cold enough to freeze. Did you notice how the water feels colder than the ice cube? The ice exposed to the salty water melts faster than other ice, so holes and channels form.

Lab 2 - Essay Example Bases cause the litmus to turn blue. Strength of a base is dependent on concentration of OH- ions produced. On the pH scale, basicity of a substance increases from 7 to 14: 7 being neutral and 14 being strongest base (one that generates maximum OH- ions when dissolved). Name two acid and bases that you often use. Acids: Milk, Orange Juice Bases: Soap, Tooth paste Cube Dimensions Surface Area (cm2) Volume (cm3) Surface Area : Volume Time Required for Complete Color Change Distance of Diffusion 1 cm X 1 cm X 1 cm 6 1 6:1 3 min 0.50 cm 1 cm X 2 cm X 2 cm 16 4 4:1 2 min 50 sec 0.30 cm 1 cm X 1 cm X 6 cm 36 6 6:1 2 min 42 sec 0.48 cm How did the surface area effect the diffusion of the cube? What about the volume? What about the surface area to volume ratio? Which of these had the greatest effect on the diffusion of the cube? Time required for complete color change is found to be approximately same for all three cubes (average time: 2 minutes 50 seconds) which concludes that rate of diffu sion of vinegar into the agar is same irrespective of shape and size. Further, volume had no impact on the time required for color change. No regular trend has been observed for distance of diffusion of vinegar inside the agar with respect to surface area or volume, when each is considered alone. Ideally, greater distance of diffusion should have been found in Cube B ( 1 cm X 2 cm X 2 cm) as compared to Cube A ( 1 cm X 1 cm X 1 cm) as it has the greater surface area (larger surface area enhances amount of diffusion); however, the irregular pattern reveals that there is a third factor that has a direct bearing on the distance of diffusion. Studying the results of the experiment, it becomes evident that surface area to volume ratio is the single parameter that majorly affects the amount of diffusion of vinegar into the agar. Cube A ( 1 cm X 1 cm X 1 cm) and Cube C (1 cm X 1 cm X 6 cm) having same surface area to volume ratio yield the same distance of diffusion. On the other hand, cub e B ( 1 cm x 2 cm x 2cm) tails at 0.3 cm. Even though greater amount of vinegar diffuses in to cube B than in cube A due to greater surface area, a larger time period is required for it to reach the center. In conclusion, the experiment demonstrates that depth of diffusion is lesser for materials having smaller surface areas to volume ratio than that with higher surface area to volume ratio. How does this experiment demonstrate the need for larger cells to divide? A cell meets its requirements for growth, repair and removal of waste materials through its cell membrane, the amount of transfer directly relating to its surface area. More so, the extent of movement of substances into a cell-towards its center- depends upon its size and volume. An increase in cell size is accompanied with an increase in requirements of the cell. More nutrients need to be diffused in and a greater amount of waste materials require to be diffused out. Consequently, a mechanism needs to be established that would allow a rapid transfer of substances through the cell membrane. As the cell is grows uncontrollably without division, the surface area to volume ratio decreases. This limits the distance to which substances diffuse into the cell, posing a restriction to the functionality of various components of the cell-especially those located towards the center. To counter this, it

Throughout the conversation all the group member appeared to be very active and motivated to give their best. We decided to have our 1st group meeting in the next class. On 29th January, we had our first meeting in the class at about 11:35 am. We had a new member added to the group. Along with the new member the rest of the group was informed and instructed about the job regarding 3710 class. The group members were asked to advise and supervise the 3710 class but not give them any ideas. Everyone in the group was comfortable with the given information. The groups mission was to collect 1000$ which will ultimately go to the SEED Program. We had two things to be worked upon, 1. To collect about 1000$ which will go to the business school for SEED Program and 2. To make the students of MGT3110 pass the finals. We started discussing amongst each other and brainstorming about different ideas. Many of us came up with unique ideas to be worked upon. As we were sharing and discussing the ideas we also started noting them down on a piece of paper. We started having individual reactions from the group member on each of the noted ideas which was a great help.

Branding Strategies Of Asda Marketing Essay

Branding Strategies Of Asda Marketing Essay Branding is a most important tool for any product or company to gain a long term market share. The aim of this study is to develop an understanding of branding and its implications in the retail market. This will include the concepts and practices of branding that are adopted by different retailers in the UK as well as the new challenges faced by these retailers in UK market. This research will identify the benefits of branding for suppliers, customers and for the retailers. I will identify the strategic approach which retailers in the UK can adopt as a role model to survive in a highly competitive market and this will include the survey of UK food and grocery retail market. I will also investigate how the changes in the market from the early beginning have changed the position of grocery supermarket chains. I will describe the in-depth branding strategies of ASDA, various operations of ASDAs stores and its competition with world-wide and UK retailers. This study will also identify and investigate the competitive position of ASDA amount other key players in UK such as TESCO, Sainsbury and Morrison. INTRODUCTION What is branding? According to the Websters dictionary a brand is defined as a mean of identification and an arbitrarily adapted name that is given by manufacturer to a product to distinguish it and it may be used and protected as trade name.  [1]   A brand is defined as a name, term, design or symbol or a combination of them intended to identify the goods and services that identifies and distinguishes a specific sellers product from a competitive product of another seller. It is also defined as a part of a product and services tangible features, the verbal indication that help customers to identify the products they want. It plays a vital role in assessment of a product or service and can add value to them. It is a word which is commonly referred to by advertisers and marketing people. Why it is important? People generally recognize a well-known brand even if they do not know about the company or its products/services. These are usually the name of businesses or the name of a product, although it can be the name of a feature or style of a product too. A good brand delivers the message clearly and motivates the buyers. There are few other terms which have been used to define branding such as brand name, brand mark, trade name or trade mark. Thus branding is very essential for companies and it is beneficial for buyers and customers. INDUSTRY BACKGROUND ASDA was formed in 1965 with a merger of two companies, Associated Dairies and the Asquith Brothers supermarket chain Queen. ASDA Stored Ltd was created a supermarket with its objectives to offer the customers permanently low prices. In 1999 ASDA was acquired by Wal-Mart Stores Inc., and ASDA became part of the worlds biggest and best retailer. Since then, ASDA also became Britains second largest supermarket. ASDA has now over 300 stores across the UK and employ 150,000 staff and its friendly service is as inextricably linked to the ASDA brand as their reputation for quality and service.  [2]   According to a recent survey, as of 1st August 2010 ASDA has 376 locations with operating income of  £638 million and ranking as second largest supermarket chain in the UK. ASDA Group Ltd., operates as one of the largest food retailers in the United Kingdom. The companys stores sell a wide variety of merchandise including food and apparel, along with house wares, music, videos and books. The company once known as a diary conglomerate was acquired by Wal-Mart Inc. in 1999. Under its new parents guidance, ASDA has been adding pharmacies, opticians, jewelry and photo departments to its stores.  [3]   ASDAS BRANDING STRATEGY According to a survey in 2004 which shows the key figures of the UK retail market, states that UK retail sales reached approximately  £246 billion in 2004. This shows that retail industry, generally, continues to show positive signs of growth. The retail industry in any country is generally a very active, fast changing sector. Thus it comprises one of the main sectors in the economy of a country, in terms of transactions and turnover; as a result, it is a highly competitive and sophisticated industry. My research proposal is about the importance of branding in retail market particularly in the UK retail, food and grocery market. I will identify the branding strategy of ASDA and its market share in the UK retail sector. Currently ASDA is using one strategy which is: In September 2010 ASDA announced that it is going to re-launch its mid-tier private label range under the new Chosen by You brand name in a bid to improve perceptions of the quality of its food. This new rang is a part of a  £100m investment which includes 200,000 UK consumers taste testing and benchmarking the products.  [4]   And now ASDA has also decided to launch their new opticians business adopting similar logos and using slogans making indirect references to the chain. ASDA ran a campaign featuring the two slogans: Be a real spec saver at ASDA Spec savings at ASDA  [5]   These strategies are helping and will help ASDA to gain consumers satisfaction. Although ASDA is already getting continuous growth with the diversification and extension of its existing stores but the retail market has become more competitive and having less market share can affect the overall ranking and position of ASDA in the international market. Therefore I will analyse and evaluate the strategic position of ASDA in comparison to other UK retailers and in conclusion there will be future strategic options suggested which aimed to strengthen its position in the highly competitive market and to gain customers satisfaction and loyalty. While using the same brand name, ASDA is also offering financial services to its customers which include: Insurance Credit cards and loans Savings Motor breakdown cover Energy supplying According a recent report at BBC (27 May 2010) ASDA has also announced plans to buy Netto for  £778m. Netto has 193 stores in the UK which will continue to trade under the Netto name for the time being but will come under the ASDA brand by mid-2011.  [6]   ASDA is continuously promoting its brand strategy and has announced that its customers will benefit from low prices on a significantly broader range of quality products, complemented by the wide range of services ASDA offer at all their small stores (ASDA Chief Executive Andy Clarke). ASDA brand George was bought by ASDA in 1995, George was started in 1990 by George Davies and it was the first supermarket clothing brand. Thus George grew and become the largest clothing retailer by volume in the UK today. This brand is also traded internationally by Wal-Mart. RESEARCH OBJECTIVES The core idea of this research to analyze the different strategies ASDA is using for its branding to compete with all the supermarkets within UK to capture a large portion of market share in retail and other relative industries. This research will also throw light on the factors to identify how these branding strategies affect customers behaviour and why they chose ASDA as compare to all other supermarkets in UK. Without an appropriate set of objectives, you can end up not only with a misguided strategy, but with an unrealistic set of goals. Increasing brand awareness for a product that already has a baseline awareness of 99 percent, for example, can be virtually impossible. If you set the wrong objectives, you set yourself up for failure (Graham 2001).  [7]   This research will emphasize the practices of ASDAs brand objectives how ASDA is using its branding to get customers loyalty and trust within the competitive market where its main rivals TESCO, Sainsbury, Morison, Marks Spenser are operating side by side as strong competitor. ASDAs brand objectives are that it is comprised of ASDAs personality, image, core competencies and characteristics. ASDAs basic framework of its brand is to pursue to put an impression on its customers that describe the company to other people. ASDA is following the strategy of its branding to build a strong credibility and have more influence on the market and to motivate customers to shop at ASDAs stores. ASDAs objectives are to be looked as a leader and not as a follower. I will explore and find out that how ASDA is defining its objectives with specific timelines and how it has been developing plans of action to achieve those objectives. RESEARCH QUESTIONS Why branding is important and what ASDA wants from its brand to do? What does ASDA wants others to know and say about its products? How ASDA can retain its top ranking position in the UK retail market? RESEARCH AIMS Identify different retail brands in UK Identify current branding strategy of ASDA Review market share of ASDA in UK retail market Analysis of competitors of ASDA Study of future practices of ASDA Recommend improved strategy for ASDA to retain its top ranking position in the UK retail market. LITERATURE REVIEW The central concern of brand building literature experienced a dramatic shift in the last decade. Branding and the role of brands, as traditionally understood, were subject to constant review and redefinition. A traditional definition of a brand was: the name, associated with one or more items in the product line, which is used to identify the source of character of the item(s) (Kotler 2000, p. 396). A literature review is very important and critical for the justification of the proposed research in order to find out different factors to identify the research area and to clarify questions of the chosen research topic (Saunders, 2007). Aaker and Joachmisthaler (2000) argued the traditional branding model where a brand management team was liable for creating and coordinating the brands management program. In these circumstances, the brand manager was not high in the companys hierarchy; his focus was the short-term financial results of single brands and single products in single markets. The basic objective was the coordination with the manufacturing and sales departments in order to solve any problem concerning sales and market share. With this strategy the responsibility of the brand was solely the concern of the marketing department (Davis 2002). In general, most companies thought that focusing on the latest and greatest advertising campaign meant focusing on the brand (Davis and Dunn 2002). The model itself was tactical and reactive rather than strategic and visionary (Aaker and Joachimsthaler 2000). The brand was always referred to as a series of tactics and never like strategy (Davis and Dunn 2002). Brand is defined as a name, term, symbol, design or any other feature or a combination of any of them. Branding is used to define, or is proposed to identify the goods or services of one seller and distinct it from those of other sellers. Branding helps to differentiate ones service from those of its competitors. It plays vital role in assessment of product and can add value to a product. It is therefore an intimate aspect of product strategy. Therefore In developing a marketing strategy for individual products, the seller has to tackle the issue of branding. According to Peter Doyle; Brands are at the very heart of marketing. When a company creates a strong brand it attracts customers preference and builds a defensive wall against competition. Marketers and sellers make different strategies for their products and most of these are associated with branding. These decisions include how to create brands, how to choose brand names, brand marks, trademarks and trade names. A brand may identify one item, a family of items or all items of that seller. Brand loyalty is an integral part of building a brand, as consumers usually have a choice of products in the same market segment, and so a successful company will use a way to keep consumers re-buying their product or coming back to their stores rather than going to their competitor. These brand loyalty-building efforts may come in the form of coupons and incentives such as many grocery chains use a technique of grocery discount cards or loss leaders, meant to draw consumers into the store, where they will hopefully buy products at discounted fare with a higher profit ratio (Kumar 2010).  [8]   SOURCES TO BE USED FOR DATA I will be using different scholars books written in different countries on branding, why it is important and work of researcher all over the world in this field. As branding is the most important factor of any business, organisation, product or service so there is a lot of information on the internet, journals and newspapers. Proper references from all the sources will be included in my work. I will also be conducting interviews from different Managers of ASDA, TESCO and Sainsbury including some customers in the stores to get much information regarding my subject and a practical experience which will help me writing a good conclusion to my proposed work. Data collection will consist of surveys, interviews and observation with ASDA Managers, employees and customers as well as journal logs from scholars. As suggested by Prof. Francis Knox I am planning to conduct multiple interviews with each participant in order to provide more in-depth data collection and opportunities for follow-up. I will utilize a qualitative evaluation for this research project leveraging subjective methods such as interviews and observations to collect substantive and relevant data. I hope that such a qualitative approach will be valuable here due to the varying experiences of the Managers and customers visiting ASDA. Recent research on subject matter will also be consulted to validate collected data. DATA ANALYSIS Data analysis is an important part of any topic as it gives an outline and understanding of the subject. In the same way I will analyse the collected data by comparing it with all the other competitors of ASDA to find out how ASDA is benefiting from its branding strategies and objectives. I believe that data analysis shows the different things discussed in topic and which one is most suitable and favourable according to the situation. Data can be collected from various sources and its analysis gives understanding and shape to the topic or field of interest. Collect necessary Data to answer questions Analyse Data Creating strategies to use results Reporting out on recommendations and conclusion RESEARCH METHODOLIGIES My research methodology requires gathering relevant data from the scholars books, online journals, newspapers and internet and to compile the databases in order to analyze the material and to arrive at a more complete understanding of the importance of branding of a company or a product. The following chart can best represent how research methodology work: Source: http://www.clientopinions.com/pages/11/Research-Methodology/ My dissertation would be based upon primary and secondary sets of information available on branding within supermarkets and my research work will be based upon both qualitative and quantitative data, for example exploring the work of researcher on branding importance for supermarkets and conducting interviews with relevant employees working as Managers and customers of ASDA supermarket. In this research I will also include the current trends of branding in different countries of the world and especially in the UK. Questionnaires carried out during my research will help me to get the facts how big chains of supermarkets and other organisations are using their brand image to get a large portion of their respective markets. On the basis of all the relevant information available branding evaluation and conclusion will be carried out. The evaluation and conclusion will also include how and why ASDA branding is better comparing to its competitors and how ASDA can better use their branding strategy all over the world. The research approach is also constructive (Jarvinen 1999, Olkkonen 1993). The positivistic approach would have required a quantitative analysis of the system (Takala Helo 2000) which would be very difficult to accomplish without disclosing some confidential business information.  [9]   This nature of research is a process of finding information; analyzing, interpreting information to deal with questions which must have certain characteristics like be controlled, systematic, rigorous, valid and critical. My research will ideally be focused on primary and secondary research on ASDA brand name and image, which will enable me to get adequate knowledge and with the help of this awareness I will work on my dissertation with no trouble. I will be able to investigate the advantages of branding and will find out what can be the problems using a brand name/images in a most competitive market for a company. During this research proposal I found out that there is plenty of information available in the journals, books and on the internet specifically for ASDA and I will use that information in the dissertation to make it more clear and acceptable. With the help of this provided information I would be able to present this in a theoretical form including data chart, comparison diagrams etc, which will help to understand my subject simply. As mentioned earlier that brand is a most important tool for any company, product or service. There are so many products in the market who do not have proper brand name or image and these products disappear from the shelves after sometime. So in my research work I will explore few of those products and will compare the quality and price to ASDAs similar products, as this experiment will discover the importance of branding. EXPECTED OUTCOMES I consider that after having a detail study on brand name/image and its importance in the retail market and research on branding strategy of ASDA and its implementation, it will be helpful for me to suggest how ASDA can improve itself amongst its competitors in the United Kingdom. As we all know that branding is perhaps the most important fact of any business, beyond product, distribution, pricing and location for any company and this build a tangible trust and loyalty amongst the customers. Brand loyalty is an essential part of building a brand name/image as customers usually have a choice of similar products in the same market segment so a successful company like ASDA will come up with a way to keep customers re-buying their products or coming back to their store again and again rather than going to its competitors. During my dissertation while conducting different interviews and surveys I will find out how ASDA is successfully implementing its branding strategy and how it can more effectively improve this with my field work on this specific topic. So I conclude this proposal with acknowledging that if brand name is used properly, ASDA can keep the large share of the market. ASDA brand name is Saving you money every day, so as far ASDA is fulfilling the requirement of its brand name, there is no doubt that this big chain of supermarket will continue enjoying a large portion of the market share in the United Kingdom. During my research proposal I have found out that ASDA has improved its operations and thus it become the second largest supermarket in the United Kingdom and this is only because it has its long term branding strategies which reviewed on regular basis and the market is compared on weekly basis on the prices and quality of the product being sold at the similar stores in the country.

Competetive Nucleophiles Essay

Introduction: The purpose of this experiment was to compare the relative nucleophilicities of chloride ions and bromide ions in two different reactions. One reaction involved n-butyl alcohol and the other involved t-pentyl alcohol. We performed the reactions and compared the percentages of alkyl chloride and alkyl bromide in the product. To perform this experiment, we used methods including heating reaction mixture under reflux, extraction using a separatory funnel, drying with anhydrous sodium sulfate, and refractometry. Experiment Scheme: First, we prepared the solvent-nucleophile medium. We combined 44mL 7.7M sulfuric acid with 4.75g ammonium chloride and 8.75g ammonium bromide, and we heated the mixture with stirring to dissolve the salts. We put 17mL into a separatory funnel for use in the second reaction, and placed the rest into a reflux apparatus for our first reaction. We performed the first reaction of the competitive nucleophiles with 1-Butanol. We added 2.5mL of 1-butanol to the solvent-nucleophile medium in the reflux apparatus with a boiling stone and heated the mixture under reflux for 75 minutes. After reflux was completed, we allowed it to cool in an ice bath, and transferred the solution to a clean separatory funnel. The different phases separated, and we drained the lower aqueous layer. We added 5mL water to organic layer, mixed and collected the lower organic layer. We extracted the organic layer with 5mL sodium bicarbonate, drained organic layer and dried with anhydrous sodium sulfate. We decanted the alkyl halide solution and set it aside to be analyzed by refractometry. We performed the second reaction of competitive nucleophiles with 2-methyl-2-butanol. We measured 2.5mL of 2-methyl-2-butanol into the separatory funnel containing 17mL of the solvent-nucleophile medium. We swirled the mixture, venting occasionally until pressure equalized, then shook it vigorously with occasional venting for 2 minutes. We then allowed phases to separate. We drained the lower aqueous layer and poured the top organic layer into a small beaker containing 0.5g sodium bicarbonate. When bubbling stopped and clear liquid was obtained, we decanted the alkyl halide and began analysis by refractometry of the products from both reactions. By refractometry, we measured the refractive index of the products and used Equation 1 and 2 to calculate the percentages of each product (Pavia, Lampman, Kriz, and Engel, Organic Chemistry Laboratory Manual p. 47-50). Reaction 1 (Pavia, Lampman, Kriz, and Engel, Organic Chemistry Laboratory Manual p. 47-50) Discussion: In this experiment we used 2 nucleophiles, the bromide ion and the chloride ion. We performed 2 reactions with these nucleophiles in equimolar concentrations, and they competed with each other for the substrate. Normally, alcohols do not react well in nucleophilic substitution reactions because the hydroxide ion (a strong base) would need to be displaced, and it is not a good leaving group. For that reason, the substitution reaction must take place in acidic solution; the alcohol must first be protonated because water is a stable molecule and a better leaving group. After protonation, the substrate reacts by either the SN1 or SN2 mechanism. 1-Butanol will react by the SN2 mechanism because it is a primary alcohol while 2-methyl-2-butanol will react by the SN1 mechanism because it is a tertiary alcohol. In Reaction 1, the major product was the alkyl bromide and the minor product was the alkyl chloride because bromine is more reactive; bromide is a stronger nucleophile. In Reaction 2, there essentially was no major product because the alkyl bromide and alkyl chloride formed in nearly equal amounts; the product was racemic. This is because it followed the SN1 reaction mechanism. The rate determining step is the loss of the H2O molecule forming a carbocation, and this step does not require a nucleophile (Pavia, Lampman, Kriz, and Engel, Organic Chemistry Laboratory Manual p. 47-50). Important methods used in this experiment included heating reaction mixture under reflux, extraction using a separatory funnel, drying with anhydrous sodium sulfate, and refractometry. When heating under reflux, we used a condenser attached to the flask that we were heating. Under reflux, our system could heat the mixture to boiling and vapors condensed and drop back into the flask. We can heat our mixture for a long time at boiling point without losing any product. In refractometry, we measured the refractive index of our product mixture, which is the ratio of the speed of light in a vacuum to the speed of light in the media of interest. We can use our measured values with the standard values to calculate the percentages of alkyl chloride and alkyl bromide. Sources of error could include the extraction process and the reading of the refractive index values. During extraction, it is possible that the phases may not have completely separated or the reactants did not fully react to form products, so some of the reactants could possibly enter into our final mixture. When finding refractive index values, it is possible to have some error when reading the value. Overall, error did not have a huge effect on our results. We could improve the procedure by being very careful to remove the entire aqueous layer during extraction so none gets into our final product for refractometry testing. In conclusion, the experiment turned out well. Our results align with the expected results. We expected that the alkyl bromide will be the major product of Reaction 1 because it followed the SN2 mechanism, and we expected that the product from Reaction 2 would be a racemic mixture because it followed the SN1 mechanism. Questions: Bromide is a stronger nucleophile because the chlorine is more electronegative than bromine, so it holds electrons in closer. Bromine is less electronegative and has more electrons, and it is able to share unpaired electrons much more easily than chlorine. References ChemSpider Chemical Database.
