Why do aldehydes and ketones have higher boiling points than hydrocarbons and ethers of comparable m

Q: What is the correct answer for CBSE12?

The correct answer is B. Aldehydes and ketones have higher boiling points than hydrocarbons and ethers of comparable molecular masses because of the presence of polar carbonyl groups, which lead to significant dipole-dipole interactions between molecules. However, they do not form intermolecular hydrogen bonds like alcohols.
