Given below are two statements:
Statement I The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses because of weak molecular association in aldehydes and ketones due to dipole-dipole interactions.
Statement II  The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of H-bonding.
In the light of the above statements, choose the most appropriate answer from the options given below:
1.  Statement I is incorrect but Statement II is correct.
2.  Both Statement I and Statement II are correct.
3.  Both Statement I and Statement II are incorrect.

Carboxylic acids have higher boiling points than aldehydes, ketones and even alcohols of comparable molecular mass. It is due to:

1. Formation of intramolecular H-bonding
2. Formation of carboxylate ion
3. More extensive association of carboxylic acid via van der waals force of attraction
4. Formation of intermolecular H-bonding
