Vedclass · Answer

(B) The Rosenmund reduction is a hydrogenation process used to convert acid chlorides into aldehydes. The reagent used is $H_2$ gas in the presence of palladium $(Pd)$ catalyst supported on barium sulfate $(BaSO_4)$. $BaSO_4$ acts as a poison to prevent the further reduction of the aldehyde to a primary alcohol. Therefore,the correct reagent is $H_2 / Pd, BaSO_4$.
