Question

During the Rosenmund reduction of acyl chlorides to aldehydes using $H_2$ gas over a Palladium catalyst, what is the exact function of the added Barium Sulfate ($BaSO_4$)?

Correct answer: C. The highly active Palladium catalyst would normally reduce the acyl chloride past the aldehyde stage to a primary alcohol. poisons the catalyst just enough to halt the reaction safely at the aldehyde.
