Vedclass · Answer

(D) In an $S_{N}1$ reaction,the rate-determining step involves the formation of a carbocation intermediate. If the initially formed carbocation is less stable,it can undergo rearrangement (via hydride or alkyl shift) to form a more stable carbocation.$A$. $CH_3-C(CH_3)_2-CH(I)-CH_3$ forms a secondary carbocation which can undergo a hydride shift to form a more stable tertiary carbocation.$B$. $1-$chloro$-2-$methylcyclohexane forms a secondary carbocation which can undergo a hydride shift to form a more stable tertiary carbocation.$C$. $3-$iodocyclohexene forms an allylic carbocation which can undergo resonance stabilization,and further rearrangement can occur to form more stable carbocations.Since all the given alkyl halides can undergo rearrangement to form more stable carbocations,the correct answer is $D$.

Which of the following alkyl halides undergoes rearrangement in an $S_{N}1$ reaction?
