Vedclass · Answer

(D) The starting material is furfuryl chloride. In the presence of $NaCN$ and under $S_N1$ conditions,the $Cl^-$ ion leaves to form a resonance-stabilized carbocation,which is the furfuryl cation. This carbocation can undergo nucleophilic attack by $CN^-$ at the $CH_2$ position to give $2-$cyanomethylfuran (Option $A$). Additionally,due to the resonance stabilization,the positive charge can be delocalized onto the ring,allowing for attack at the ring carbon,leading to rearranged products like the one shown in Option $C$. Therefore,both $(A)$ and $(C)$ are possible products under these conditions.
