Vedclass · Answer

(C) Nucleophilic substitution reactions in haloalkenes depend on the stability of the transition state and the nature of the $C-X$ bond.In $C_6H_5Cl$,$CH_2=CH-Cl$,and $CH_3CH=CH-Cl$,the chlorine atom is directly attached to an $sp^2$ hybridized carbon atom,which makes the $C-X$ bond stronger due to partial double bond character caused by resonance.In $ClCH_2-CH=CH_2$ (allyl chloride),the chlorine is attached to an $sp^3$ hybridized carbon atom.Upon loss of the chloride ion,the resulting allyl carbocation $(CH_2=CH-CH_2^+)$ is resonance stabilized.Therefore,$ClCH_2-CH=CH_2$ is the most reactive towards nucleophilic substitution.
