Question:
Why do ketones and carboxylic acids have higher boiling points as compared to aldehydes?
Why do ketones and carboxylic acids have higher boiling points as compared to aldehydes?
Show Hint
Intermolecular hydrogen bonding increases the boiling point of compounds.
Updated On: Apr 23, 2025
- Due to \(\text{—CHO}\) group
- Due to Fazan’s rule
- Due to intermolecular hydrogen bonding
- Due to intramolecular hydrogen bonding
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The higher boiling point of ketones and carboxylic acids, compared to aldehydes, can be attributed to intermolecular hydrogen bonding. Aldehydes have only dipole-dipole interactions, whereas carboxylic acids and ketones experience stronger interactions due to the presence of the —CHO group, which facilitates hydrogen bonding between molecules. Thus, the correct answer is Option (A).
