Vedclass · Answer

(B) Dehydrohalogenation involves the elimination of a hydrogen halide $(HX)$ from an alkyl halide to form an alkene.The rate-determining step in this reaction involves the breaking of the $C-X$ bond.The strength of the $C-X$ bond decreases as the size of the halogen atom increases $(C-F > C-Cl > C-Br > C-I)$.Since the $C-I$ bond is the weakest,it breaks most easily,making alkyl iodides the most reactive towards dehydrohalogenation.Therefore,the correct order of reactivity is $R-I > R-Br > R-Cl > R-F$.
