Solution

Verified by Toppr

Isocyanide test can be given by aromatic or aliphatic primary amines.
Thus, ethyl amine, aniline and alpha phenyl propylamine can give isocyanide test.
This test is also called carbylamine test.
Ethyl phenyl amine is a secondary amine. Hence, it will not give this test.
