Which substance ( HBr or HF ) has the higher boiling point?

Question

Its HF but chose one of the most appropriate reason.
1. Both substances are nonpolar but the higher boiling includes hydrogen bonding 2. Both substances are nonpolar but the higher boiling is more polarizable
3. The higher boiling substance is polar and the other is not
4. The lower boiling substance is polar and the other is not
5. The higher boiling substance has smaller vander Waals forces than the lower boiling
6. The higher boiling substance has greater vander Waals forces than the lower boiling
7. The higher boiling substance is ionic and the other is not
8. The lower boiling substance is ionic and the other is not
9. The higher boiling substance has hydrogen bonds and the other does not 10. The lower boiling substance has hydrogen bonds and the other does not 11. Both substances are ionic but the higher boiling has a larger cohesive energy
12. Both substances are ionic but the lower boiling has a larger cohesive energy
13. The higher boiling substance is ionic and the other is not. Ionic bonds are stronger than hydrogen bonds
14. The lower boiling substance is ionic and the other is not. Ionic bonds are weaker than hydrogen bonds
15. The higher boiling substance is ionic and the other is not. Ionic bonds are stronger than vander Waals forces
16.The lower boiling substance is ionic and the other is not. Ionic bonds are weaker than vander Waals forces

Answer 1

Most of these statements are not true. #5 is true but not the reason I would choose. I would pick 9.

Answer 2

thnx you are correct
