# 13.7     Write short notes on the following:                (v) Ammonolysis

Ammonolysis-
When an alkyl or benzyl halide is going to react with the solution of ammonia(an ethanolic) undergoes nucleophilic substitution reaction in which the halogen atom is replaced by an amino ($-NH_{2}$) group. This process of cleavage of the carbon-halogen(C-X) bond by ammonia molecule is known as ammonolysis.

When this substituted ammonium salt is treated with a strong base it gives primary amine
$RN^{+}H_{3}X^{-}+NaOH\rightarrow R-NH_{2}+H_{2}O+NaX$

• Above primary amine is behaves as a nucleophile and can further react with an alkyl halide to form secondary and tertiary amines and finally quaternary ammonium salt.
