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.

- Carbohydrates are polyhydroxy aldehydes or ketones that represent enormous structural diversity in terms of the arrangement of atoms in space, resulting in hundreds of stereoisomers. Although the chemical properties of most stereoisomers may not be very different, their metabolic rate and utilization in biological systems is significantly different and known to influence the overall carbohydrate metabolism. Structural variants, which arise due to a different arrangement of atoms in three-dimensional space are known as stereoisomers. The number of stereoisomers can be theoretically estimated by using the formula 2n, where ‘n’ is the number of stereocenters or asymmetric (chiral) carbon atoms in a molecule. Out of these stereoisomers, there are some structures, which are mirror images of each other, and they are referred to as enantiomers.
