Vedclass · Answer

(C) The reaction of alkyl halides with ammonia is a nucleophilic substitution reaction $(S_N2)$.In this reaction,the halide ion $(X^-)$ acts as a leaving group.The reactivity of alkyl halides depends on the strength of the $C-X$ bond.The bond dissociation energy decreases as the size of the halogen atom increases,making the $C-I$ bond the weakest and the $C-Cl$ bond the strongest.Therefore,the leaving group ability follows the order: $I^- > Br^- > Cl^-$.Thus,the order of reactivity of alkyl halides with ammonia is $R-I > R-Br > R-Cl$.
