What is the product formed on Rosenmund reduction of benzoyl chloride ?
Options
- ABenzene
- BBenzyl alcohol
- CBenzaldehyde
- DChlorobenzene
Correct answer
C. Benzaldehyde
Step-by-step solution
Rosenmund reduction is the catalytic hydrogenation of an acid chloride to an aldehyde. The reagent used is hydrogen gas in the presence of a palladium catalyst supported on barium sulfate ( H₂ / Pd-BaSO₄ ). When benzoyl chloride ( C₆H₅COCl ) is subjected to Rosenmund reduction, it is reduced to benzaldehyde ( C₆H₅CHO ). The reaction is: C₆H₅COCl + H₂ Pd/BaSO₄ C₆H₅CHO + HCl Therefore, the product formed is benzaldehyde. Answer: Benzaldehyde
