Ester compounds often have a sweet, pleasant odor. Many characteristic fruit scents are largely due to the natural presence of one or more ester compounds. As such, artificial scents for foods are often composed of complex mixtures of various esters. The exact identity and ratio of ingredients that compose a particular scent are closely guarded secrets in the food and fragrance industry. Suppose that you are a chemist working for a company that is creating a new line of air fresheners. The company is considering three scents: apple, pear, and pineapple. The project manager has asked you to prepare the ester compounds that are largely responsible for these scents. The structural formulas for these ester compounds are shown here: To prepare these esters, you have been given the alcohols listed in the table and an adequate supply of all other necessary reagents, solvents, and equipment. Use the structural formulas of the alcohols and information in the table to answer these questions: a. Provide a name for each ester that you will prepare. b. Draw the structure of each alcohol listed in the table. c. Determine the procedure you will use to prepare each ester, using the reactions found in this chapter. (Hint: Recall that esters are derived from a carboxylic acid and an alcohol.) d. Calculate the cost to prepare 100.0 g of each ester. Which one will be the most expensive to prepare? Which ester will be the least expensive? (Consider only the cost of the alcohols in the table, and disregard the costs of other reagents. Assume 100% yield for all reactions.)
