Choose the amide which on reduction with `LiAIH_4` yields a secondary amine

Options

A. ethanamide
B. N-methylethanamide
C. N,N-dimethylethanamide
D. phenylmethanamide

Answer

B

Explanation

Secondary amides such as N-methylethanamide on reduction with `LiAIH_4` give secondary amines
`underset"N-methylethanamide"(CH_3CONHCH_3)+[H] overset(LiAlH_4)to underset(2^@ "amine")(CH_3CH_2NHCH_3)+ H_2O`
