Question
Cyanohydrins are important intermediates in the synthesis of alpha-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 acid using aqueous base. When a cyanohydrins is treated with aqueous base, however, the original carbonyl compound is isolated. Refer to instructions. The reaction of an aldehyde with hydrogen cyanide is an example of _____ reaction. a. a nucleophilic substitution b. an electrophilic addition c. an electrophilic substitution d. a nucleophilic additionExplanation / Answer
The reaction of an aldehyde with Hydrogen Cyanide is an example of A NUCLEOPHILIC ADDITION reaction.
Here, Hydrogen cyanide undergoes nucleophilic addition to the carbon-oxygen double bond in aldehyde to produce compounds known as hydroxynitriles.
So the correct option is D
