Which of the following catalyst is used in Rosenmund reaction?
- A \(\mathrm{Cu}_{2} \mathrm{Cl}_{2}\)
- B \(\mathrm{CS}_{2}\)
- C \(\mathrm{Pd}-\mathrm{BaSO}_{4}\)
- D \(\mathrm{V}_{2} \mathrm{O}_{5}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{Pd}-\mathrm{BaSO}_{4}\)
Step-by-step Solution
Detailed explanation
When benzoyl chloride is hydrogenated in the presence palladium on barium sulphate \(\left(\mathrm{Pd} / \mathrm{BaSO}_{4}\right)\), benzaldehyde is obtained. This reaction is called Rosenmund reduction.
