Vedclass · Answer

(C) The $S_N 1$ reaction rate depends upon the stability of the carbocation intermediate formed in the rate-determining step. Higher stability of the carbocation leads to higher reactivity.The carbocation intermediates formed are:$1$. $CH_3-CO-CH_2^+$ (Least stable due to the strong electron-withdrawing effect of the carbonyl group).$2$. $CH_3-CH_2-CH_2^+$ ($1^\circ$ carbocation).$3$. $(CH_3)_3C^+$ ($3^\circ$ carbocation,most stable due to hyperconjugation and inductive effect).Thus,the order of stability of the carbocations is $(CH_3)_3C^+ > CH_3-CH_2-CH_2^+ > CH_3-CO-CH_2^+$.Therefore,the order of $S_N 1$ reactivity is $3 > 2 > 1$.
