Choose the amide which on reduction with LiAlH4 yields a secondary amine

Question

Choose the amide which on reduction with LiAlH4 yields a secondary amine (A) Ethanamide (B) N-Methylethanamide (C) N, N-dimethylethanamide (D) Phenylmethanamide

Tardigrade Admin · Accepted Answer

Secondary amides such as N-methylethanamide on reduction with

L i A l H_{4}

give secondary amines.

N - m e t h y l e t hanami d e C H_{3} CON H C H_{3} + [H] L i A l H_{4}

2^{\circ} amin e C H_{3} C H_{2} N H C H_{3} + H_{2} O

Q. Choose the amide which on reduction with $L i A l H_{4}$ yields a secondary amine

Ethanamide

$N$ -Methylethanamide

$N, N$ -dimethylethanamide

Phenylmethanamide

Butanamide
