2. Consider the data below to answer the following questions.
Cyanohydrins are important intermediates in the synthesis of α-hydroxycarboxylic acids from ketones and
aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid.
Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin
is treated with aqueous base the original carbonyl compound is isolated.
