Vedclass · Answer

(C) The $SN^1$ reaction mechanism proceeds via the formation of a carbocation intermediate. The rate of $SN^1$ reaction depends on the stability of the carbocation formed.$A$. $CH_3-Br$ forms a primary methyl carbocation,which is highly unstable and does not undergo $SN^1$.$B$. $Ph-Br$ (Bromobenzene) does not undergo $SN^1$ because the $C-Br$ bond has partial double bond character due to resonance,and the phenyl cation is extremely unstable.$C$. $CH_2=CH-CH_2-Br$ forms an allyl carbocation $(CH_2=CH-CH_2^+)$,which is resonance-stabilized. This reaction can proceed via $SN^1$ in the presence of a polar protic solvent like $H_2O$.$D$. $1-$bromobicyclo[$2.2$.$1$]heptane cannot undergo $SN^1$ because the bridgehead carbon cannot achieve the planar geometry required for a carbocation intermediate (Bredt's rule).Therefore,the correct option is $C$.

In which of the following reactions does an $SN^1$ reaction take place?
