Vedclass · Answer

(A) The rate of $S_N 1$ reaction depends on the stability of the carbocation intermediate formed after the departure of the leaving group.In $H_2C=CH-CH_2Cl$,the carbocation formed is $H_2C=CH-CH_2^+$,which is resonance-stabilized by the adjacent double bond.Chlorobenzene and $CH_2=CHCl$ are vinylic/aryl halides where the $C-Cl$ bond has partial double bond character,making them very unreactive towards $S_N 1$.$CH_3CH_2Cl$ forms a primary carbocation,which is less stable than the resonance-stabilized allylic carbocation.Therefore,$H_2C=CH-CH_2Cl$ reacts fastest.
