When ethyl amine reacts with chloroform in the presence of alcoholic potash, then ethylisocynide is formed. This reaction is known as carbyl amine reaction.

Ethyl amine C_{2} H_{5} - N H_{2} + Chloroform C H C l_{3} + 3 K O H \to C_{2} H_{5} - NC + 3 K Cl + 3 H_{2} O

Ethyl isocyanide (bad smelling compound)
