Question

Reductions of carboxylic acid derivatives might be expected to lead either to aldehydes or alcohols, functional groups having a lower oxidation state of the carboxyl carbon by which of the following?

• A. Catalytic hydrogenation
• B. Complex metal hydride reductions
• C. Diborane reduction
• D. All of the above

Answer 1

The correct option is D All of the above

All the carboxylic acid/derivatives give less oxidation state groups with reducing agents.
