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.
