Answer:
alkyl halide + 2 (ammonia) → alkyl amine + ammonium halide
Explanation:
In this type of preparation of alkyl amine this process works through substitution nucleophilic second order reaction and the nucleophile in this case is the ammonia and the leaving group will be the chloride ion
When ammonia attacks opposite to the way in which leaving group leaves, the chloride ion will be leaved and the nitrogen attains positive charge
So one of the hydrogen attached to the nitrogen will be removed and as there is another mole of ammonia and as ammonia is a base, it takes that hydrogen and it will form ammonium ion and to this ion chloride ion will get attracted as both have opposite charges and at last alkyl amine and ammonium halide will be formed
