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.

$A$. $C_6H_5COCl + H_2 \xrightarrow{Pd-BaSO_4} C_6H_5CHO$	$I$. Gattermann-Koch reaction
$B$. $CH_3CN + SnCl_2 + HCl \rightarrow CH_3CHO$	$II$. Etard reaction
$C$. $C_6H_5CH_3 + CrO_2Cl_2 \rightarrow C_6H_5CHO$	$III$. Stephen reaction
$D$. $C_6H_6 + CO + HCl \xrightarrow{AlCl_3} C_6H_5CHO$	$IV$. Rosenmund reaction
