NEET Chemistry: Aldehydes and Ketones questions with solutions

Q1. On reduction of glycolic acid with \( \boldsymbol{H} \boldsymbol{I} \) the product formed is:

1. acetic acid
2. iodo aectic acid
3. formic acid
4. none of these

Answer: formic acid

Glycolic acid is hydroxyacetic acid, HOCH2COOH. On reduction with HI, the alcohol part is reduced and the two-carbon acid effectively gives the one-carbon acid, formic acid, as the product listed.
