Rosenmund reduction
-
The following conversion (an acid chloride, $C_6H_5COCl$, converted to benzaldehyde $C_6H_5CHO$ using $H_2/Pd-BaSO_4$) is known as:A Stephen reactionB Gattermann-Koch reactionC Etard reactionD Rosenmund reactionSelective reduction of an acid chloride to an aldehyde using $H_2$ over a Pd-$BaSO_4$ (poisoned palladium) catalyst is known as the Rosenmund reaction.

Identify compound (A) in the following reaction: $A\xrightarrow{H_2/Pd\text{-}BaSO_4}C_6H_5CHO$ (benzaldehyde)A Benzoic acidB Benzoyl chlorideC TolueneD AcetophenoneIn the Rosenmund reduction, an acid chloride is selectively reduced to an aldehyde using $H_2$ over a poisoned Pd-$BaSO_4$ catalyst. So A must be benzoyl chloride ($C_6H_5COCl$), which is reduced to benzaldehyde.
