On Hydrolysis with dilute HCl, ethanenitrile gives acetic acid through:
Correct answer: B. Acetamide
- A. Formamide
- B. Acetamide
- C. Benzoic acid
- D. Acetaldehyde
Explanation
Option B is correct since nitriles form carboxylic acids via an amide intermediate. Option A is incorrect since hydrogen cyanide will give formamide intermediate to form methanoic acid. Option C is incorrect since benzoic acid will be formed after the formation of phenyl amide intermediate. Option D is incorrect since aldehydes are not formed as an intermediate between nitriles and carboxylic acids.

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.
