Question

Match each type of reduction to its reagent:

• A. Clemmensen Reduction → Zinc amalgam with hydrochloric acid
• B. Wolff-Kishner Reduction → Hydrazine and potassium hydroxide with heat
• C. Rosenmund Reduction → Hydrogen gas with palladium on barium sulfate

Hint:

Always associate the type of reduction with the environment and reagents. Clemmensen is acidic, Wolff-Kishner is basic, and Rosenmund uses palladium.

Answer 1

The Correct Option is A

Step 1: Understanding each reduction.
- Clemmensen reduction is carried out under acidic conditions, typically using zinc amalgam and hydrochloric acid.
- Wolff-Kishner reduction is performed under basic conditions, using hydrazine and potassium hydroxide with heat.
- Rosenmund reduction involves hydrogen gas and palladium on barium sulfate, often used to reduce acyl chlorides to aldehydes.
Step 2: Conclusion.
Thus, the correct matches are: (A) Clemmensen Reduction → Zinc amalgam with hydrochloric acid (B) Wolff-Kishner Reduction → Hydrazine and potassium hydroxide with heat (C) Rosenmund Reduction → Hydrogen gas with palladium on barium sulfate
