Among the amines of formula $C X_{3} H X_{9} N$ , the one that does not give the carbylamine test and reacts with benzenesulfonyl chloride to give a product insoluble in aqueous alkali is

Apropan-2-amine
BN-methylethanamine
Cpropan-1-amine
DN,N-dimethylmethanamine

Answer: B

The two primary amines give the carbylamine test and give sulfonamides that dissolve in alkali. The tertiary amine does not form a stable sulfonamide. The secondary amine

CH X_{3} NHCH X_{2} CH X_{3}

gives an N,N-disubstituted sulfonamide that has no acidic N-H and is insoluble in alkali (Hinsberg test).
