Question

On reduction of glycolic acid with HI, the product formed is

• A. acetic acid
• B. iodo-acetic acid
• C. formic acid
• D. None of these

Hint:

Reduction of acids with HI typically leads to the formation of corresponding alcohols or aldehydes, depending on the reactant.

Answer 1

The Correct Option is A

The reduction of glycolic acid with hydroiodic acid (HI) leads to the formation of acetic acid.
HI reduces the carboxyl group (-COOH) of glycolic acid to a -CHOH group, resulting in acetic acid.
