An acid anhydride reacts with an alcohol to form one
ester and one carboxylic acid. An unsymmetrical acid anhydride can
react with alcohol at either carbonyl carbon, so there are two
possible esters and two possible carboxylic acids.

2. If one were esterifying an expensive alcohol with an expensive carboxylic acid derivative, would it be wiser to use the acid chloride or acid anhydride reagent? Why? 3. Why is so much NaOH used in the extraction? Recall that only four drops (small amount) of sulfuric acid were used as a catalyst. Esters are an important class of organic molecules, which are formally derived from alcohols and carboxylic acids. Esters occur widely in nature and are often an important...
