CH3CN+ (H2O, H+)→ A+ (H2O, H+)→CH3COOH. Predict "A" among the following:
Correct answer: B. CH3CONH2
- A. CH3CH2NH2
- B. CH3CONH2
- C. NH2CONH2
- D. CH3COOH
Explanation
The acid-catalyzed hydrolysis of a nitrile proceeds in two stages. The first stage produces an amide as an intermediate (A = acetamide, CH3CONH2). Further hydrolysis. of the amide then yields the carboxylic acid.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
