Vedclass · Answer

(B) Dehydrohalogenation is a $\beta$-elimination reaction where an alkyl halide reacts with a strong base to form an alkene. The rate of this reaction depends on the strength of the $C-X$ bond. The bond dissociation energy follows the order $C-F > C-Cl > C-Br > C-I$. Since the $C-I$ bond is the weakest,it is the easiest to break,making the alkyl iodide the most reactive. Therefore,the order of reactivity is $R-I > R-Br > R-Cl > R-F$.

The order of reactivity of alkyl halides for dehydrohalogenation is:
