A compound Z with molecular formula `C_(3)H_(9)N` reacts with `C_(6)H_(5)SO_(2)Cl` to give a solid, insoluble in alkali. Identify Z.

Explanation

Z is an aliphatic amine and on treatment `C_(6)H_(5)SO_(2)CI` gives a solid, insoluble in alkali. Therefore, the product does not have a replaceable hydrogen attached to N-atom. Thus, the amine must be a secondary amine. The only `2^(@)` amine having the molecular formula `C_(3)H_(9)N` is ethylmethylamine. Hence, the compound Z is `CH_(3)CH_(2)NHCH_(3)`.
