Can Acetone hydrogen bond with itself? why does it have a lower boiling point than cyclohexane?

Acetone (CH₃-CO-CH₃) cannot form hydrogen bond with itself. Although the O atom in acetone molecule is negative enough, none of the six H atoms is positive enough to form hydrogen bond.

Both acetone and cyclohexane (C₆H₁₂) are simple molecular compounds. The van der Waals' forces in cyclohexane are stronger than the van der Waals' forces in acetone because cyclohexane has a greater molecular size. Hence, acetone has a lower boiling point.

All things considered, Acetone has a notably higher boiling point compared to cyclohexane.
