Vedclass · Answer

(B) The rate of $S_N1$ reaction depends on the stability of the carbocation intermediate formed after the departure of the leaving group $(Br^-)$.$A$: Forms a primary $(1^{\circ})$ carbocation,which is the least stable.$B$: Forms an allylic carbocation $(CH_2=CH-CH^+(CH_3))$,which is resonance-stabilized and thus the most stable.$C$: Forms a secondary $(2^{\circ})$ carbocation,which is more stable than a primary carbocation but less stable than a resonance-stabilized allylic carbocation.Therefore,the stability order of the carbocations is $B > C > A$,which is also the order of $S_N1$ reactivity.

Consider the following bromides. What is the correct order of $S_N1$ reactivity?
