    Stronger intermolecular forces imply higher boiling points, so you need to figure out which has the strongest intermolecular forces and which has the weakest.

    Hydrogen fluoride: strongest IMF is H-bonding

    Hydrogen: strongest IMF is dispersion

    Potassium chloride: strongest IMF is dipole-dipole

    In terms of strength H-bonding > dipole-dipole > dispersion

    Because Hydrogen fluoride has the strongest intermolecular forces, it has the highest boiling point. Hydrogen has the weakest IMF meaning that it has the lowest boiling point. Potassium chloride is in the middle.
