Question

CH3CH2Cl into CH3CH2CH2NH2

Answer

​

Answer 1

Ethyl chloride reacts with sodium cyanide to form propionitrile. Cl is displaced with -CN.

Hydrogenation in presence of Ni reduces cyano group to amino group. Acetylation with acetic anhydride gives the final product Z in which the amino group is acetylated.
