Question

This reduction reaction is known as:

• A. Etard Reaction
• B. Stephen's Reaction
• C. Wolff Kishner Reduction
• D. Rosenmund reduction

Answer 1

The Correct Option is D

Step 1. Identify the Reaction Components: The reaction involves the reduction of an acid chloride to an aldehyde using H₂ gas in the presence of palladium on barium sulphate (Pd-BaSO₄).

Step 2. Characteristics of Rosenmund Reduction: This specific reduction, where an acid chloride is reduced to an aldehyde, is known as the Rosenmund reduction. In this process, the use of Pd-BaSO₄ prevents further reduction of the aldehyde to an alcohol.

Step 3. Conclude with the Recognized Reaction: Thus, the partial reduction of the acid chloride to an aldehyde in this reaction confirms it as a Rosenmund reduction.
