If ethanoic acid is to be prepared by hydrolysis of alkane nitriles, which of the following can be the reagent to be hydrolyzed?
Correct answer: A. CH3CN
- A. CH3CN
- B. CH3CH2CN
- C. HCN
- D. NaCN+HCI
Explanation
Hydrolysis of an alkanenitrile on boiling with mineral acids or alkalis yields corresponding carboxylic acid. CH3CN + 2H2O + HCl →H+ + CH3-CHO-NH2 →NH4Cl++CH3COOH

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.
