Vedclass · Answer

(D) Let us analyze each reaction:$A$. Gattermann-Koch reaction: Benzene reacts with $CO + HCl$ in the presence of $Anhydrous \ AlCl_3 / CuCl$ to give benzaldehyde. The reaction with $HCN + HCl$ (Gattermann reaction) also yields benzaldehyde.$B$. Etard reaction: Toluene reacts with chromyl chloride $(CrO_2Cl_2)$ followed by hydrolysis to give benzaldehyde.$C$. Toluene reacts with chromic oxide $(CrO_3)$ in acetic anhydride to form benzylidene diacetate,which on hydrolysis gives benzaldehyde.$D$. Reimer-Tiemann reaction: Phenol reacts with $CHCl_3$ and $KOH$ to give salicylaldehyde (o-hydroxybenzaldehyde),not benzaldehyde.
