Question:
CH3CH2CHO and CH3CH2COOH can be distinguished by:
CH3CH2CHO and CH3CH2COOH can be distinguished by:
Show Hint
Sodium bicarbonate is used to distinguish carboxylic acids from aldehydes because it reacts with carboxylic acids to form carbon dioxide gas.

- Sodium bicarbonate test
- Hinsberg test
- Iodoform test
- Lucas test
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The sodium bicarbonate test is used to distinguish between aldehydes (which react with sodium bicarbonate to form carboxylate anions) and carboxylic acids. CH3CH2COOH (a carboxylic acid) reacts with sodium bicarbonate, while CH3CH2CHO (an aldehyde) does not.
