Vedclass · Answer

(C) The $S_{N}2$ reaction rate is significantly enhanced in allylic halides due to the stabilization of the transition state by the adjacent double bond. $4-$Chlorobut$-1-$ene $(CH_2=CH-CH_2-CH_2Cl)$ is a primary alkyl halide,but it is also an allylic halide because the chlorine atom is attached to a carbon adjacent to the double bond ($CH_2=CH-CH_2-Cl$ is the structure of $3-$chloroprop$-1-$ene,but here $4-$chlorobut$-1-$ene is $CH_2=CH-CH_2-CH_2Cl$). Wait,let us re-evaluate: $1-$Chlorobut$-2-$ene $(CH_3-CH=CH-CH_2Cl)$ is a primary allylic halide. Primary allylic halides are highly reactive towards $S_{N}2$ reactions due to the resonance stabilization of the transition state. Therefore,$1-$Chlorobut$-2-$ene is the most reactive among the given options.
