Vedclass · Answer

(B) The reactivity of alkyl halides towards $S_N1$ reaction depends on the stability of the carbocation intermediate formed after the departure of the leaving group $(Cl^-)$.$(i)$ Forms a primary $(1^{\circ})$ carbocation: $Cyclopropyl-CH_2^+$.(ii) Forms a tertiary $(3^{\circ})$ carbocation: $(Cyclopropyl)_3C^+$.(iii) Forms a secondary $(2^{\circ})$ carbocation: $(Cyclopropyl)_2CH^+$.Cyclopropyl groups provide significant stabilization to the adjacent carbocation through conjugation with the bent bonds of the cyclopropyl ring (often described as homoaromatic or through-ring conjugation). As the number of cyclopropyl groups increases,the stability of the resulting carbocation increases significantly due to increased resonance-like stabilization.Therefore,the stability order of the carbocations is: $(ii) > (iii) > (i)$.Consequently,the reactivity order for $S_N1$ is: $(ii) > (iii) > (i)$.
