Vedclass · Answer

(A) For a given alkyl group,the order of reactivity towards nucleophilic substitution is determined by the strength of the carbon-halogen bond.The bond dissociation energy decreases as the size of the halogen atom increases $(I > Br > Cl > F)$.Since the $C-I$ bond is the weakest,it is the easiest to break,making alkyl iodides the most reactive.Therefore,the correct order of reactivity is $R-I > R-Br > R-Cl$.

The order of reactivity of the given haloalkanes towards nucleophiles is:
