Step-by-step solution
The carbylamine test is a characteristic test for primary amines. When a primary amine is heated with chloroform and alcoholic potassium hydroxide, it forms an isocyanide (carbylamine) which has a characteristic foul smell. The reaction is given by: R-NH_2 + CHCl_3 + 3KOH R-NC + 3KCl + 3H_2O Secondary and tertiary amines do not give this test. Answer: Primary amine
