Question

zpupster · Answer

This is the characteristic reaction of primary amines. Primary amines on reacting with chloroform and potassium hydroxide form iso-cyanides a foul smell gas which is often used to identify primary amine group in an organic compound. Secondary and tertiary amines will not give this test.

if you need the mechanism google -carbylamine reaction
