Step-by-step solution
Substituted ammonium salt is formed when chloroalkane reacted with excess of NH 3 , which on reaction with NaOH gives 1 , 4 - diaminobutane . The carbon - halogen bond in alkyl halides can be easily cleaved by a nucleophile. Hence, an alkyl halide on reaction with an ethanolic solution of ammonia undergoes a nucleophilic substitution reaction in which the halogen atom is replaced by an amino group. This process of cleavage of the C – X bond by ammonia molecule is known as ammonolysis. Substituted ammonium salt on r
