$CH_3-CH_2-CH_2-Cl$

Vedclass · Answer

(B) The rate of dehydrohalogenation depends on the strength of the $C-X$ bond. The bond dissociation energy follows the order $C-Cl > C-Br > C-I$. Since the $C-Cl$ bond is the strongest,it is the most difficult to break,making the rate of dehydrohalogenation the slowest for alkyl chlorides compared to alkyl bromides and alkyl iodides. Among the given options,$CH_3-CH_2-CH_2-Cl$ has the strongest $C-X$ bond,resulting in the lowest rate of dehydrohalogenation.
