Updated On: Jun 26, 2026
- Rosenmund reduction
- Etard reaction
- Stephen reaction
- Gatterman reaction
- Gatterman-Koch reaction
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Identify the reaction used for the selective partial reduction of acid chlorides to aldehydes.
Step 2: Meaning
The Rosenmund reduction uses $H_2$ gas with a Palladium catalyst supported on Barium Sulfate ($Pd/BaSO_4$), partially "poisoned" by sulfur or quinoline.
Step 3: Analysis
This poisoning prevents the aldehyde from being further reduced to a primary alcohol.
Step 4: Conclusion
Rosenmund reduction is the specific name for this conversion. Final Answer: (A)
