HF has a higher boiling point than HCl because of:
Correct answer: C. Hydrogen bonding
- A. Dipole-dipole interactions
- B. Ion-dipole interactions
- C. Hydrogen bonding
- D. London-dispersion forces
Explanation
HF has a higher boiling point than HCl because of the hydrogen bonding that exists between HF molecules. HCl has dipole-dipole intermolecular interactions. Out of the two, hydrogen bonding is stronger, hence, the greater boiling point of HF.

About Hydrogen Bonding
Hydrogen bonding is the strong attraction between hydrogen attached to nitrogen, oxygen or fluorine and an electronegative atom in the same or another molecule. It explains unusual boiling points, viscosity, surface tension, water's properties and the difference between intermolecular and intramolecular hydrogen bonding.
