Which from following amines when heated with ethanolic KOH and chloroform does NOT produce foul smell ?
B. N , N - Dimethyl aniline
The reaction of an amine with chloroform and ethanolic KOH to produce a foul-smelling compound is known as the carbylamine test or isocyanide test. This test is given only by primary aliphatic and primary aromatic amines. Secondary and tertiary amines do not respond to this test. Benzenamine is a primary aromatic amine. Propan-2-amine is a primary aliphatic amine. Phenylmethanamine is a primary aliphatic amine. N,N-Dimethyl aniline is a tertiary amine, so it does not give the carbylamine test and will not produce a foul smell. Answer: N , N - Dimethyl aniline
