1. Write the overall reaction for our esterification reaction, and its mechanism. 2. Using the "rule of six", predict the solubilities in water of benzoic acid, methanol, and methyl benzoate. 3. If the 4.0 g of benzoic acid used in this reaction is limiting, what mass of methyl benzoate is predicted to be formed if you achieve 100% yield? Show your calculation. In this lab, we will produce and ester from benzoic acid and methanol. The process, called Fischer esterification, involves heating the acid with the alcohol in the presence of an acid catalyst. The mechanism (illustrated for butanoic acid and ethanol) is shown below.

5. The goal is to convince an investor to invest in your company so that you can build a factory to make ester compounds. For example, you could make hexyl pentanoate, and sell it for use in perfumes and make the investor money. You must come up with a compound that you can make and sell. You can use your textbooks and the internet as resources. At the end of your research, you must have the compound table filled out.
