Write chemical equations for the following reactions:
(i) Reaction of ethanolic `NH_(3)` with `C_(2)H_(5)Cl.`
(ii) Ammonolysis of benzyl chloride and reaction of amine so formed with two moles of `CH_(3)Cl.`

Explanation

`underset("Chloroethane")(C_(2)H_(5)-Cl) overset(NH_(3)) to underset("Ethanamine")(C_(2)H_(5)-NH_(2)) overset(C_(2)H_(2)-Cl) to underset(N-"Ethylethanamine")(C_(2)H_(5)-overset(H)overset(|)N-C_(2)H_(5)) overset(C_(2)H_(5)-Cl)to underset(N,N-"Diethylethanamine")(C_(2)H_(5)-underset(C_(2)H_(5))underset(|)N-C_(2)H_(5))`
`underset("Benzylchloride")(C_(6)H_(6)-CH_(2)-Cl)overset(NH_(3)) to underset("Benzylamine")(C_(6)H_(5)-CH_(2)-NH_(2))overset(2CH_(3)Cl) to underset("N,N-Dimethylphenylmethananmine")(C_(6)H_(5)-CH_(2)underset(CH_(3))underset(|)(N)-CH_(3))`
