Can
you check my answers please?
To answer the questions below use the following information: Cyanohydrins are important intermediates in the synthesis of c-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 OH CHCOOH HO CN OBU H HCEN H NAOH H20...
