Question
Why do aldehydes and ketones have lower boiling points than alcohols of similar molecular weight?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Alcohols have O-H bonds and can form strong intermolecular hydrogen bonds, while aldehydes and ketones lack O-H bonds and only have dipole-dipole interactions.
Hint
No O-H, no H-bonding between molecules.
