Ethanamine is heated with CHClX3 and alcoholic KOH to give X. X is reduced with HX2 over Ni to give Y. Y is
Apropan-1-amine
Bethanamine
CN,N-dimethylethanamine
DN-methylethanamine
Answer: D
The carbylamine reaction converts CHX3CHX2NHX2 into ethyl isocyanide, CHX3CHX2−NC (X). Catalytic hydrogenation of R−NC gives R−NH−CHX3, so Y = CHX3CHX2NHCHX3.
