The variation of the boiling points of the hydrogen halides is in the order HF > HI > HBr > HCl.

What explains the higher boiling point of hydrogen fluoride ?

  • Option 1)

    The electronegativity of fluorine is much higher than for other elements in the group.

  • Option 2)

    There is strong hydrogen bonding between HF molecules.

  • Option 3)

    The bond energy of HF molecules is greater than in other hydrogen halides.

  • Option 4)

    The effect of nuclear shielding is much reduced in fluorine which polarises the HF molecule.

As we discussed in the

Boiling point of Hydride -

HF>HI>HBr>HCl

- wherein

Boiling point of HF is due to H-Bond 

 

 Higher boiling point of HF is due to strong Hydrogen bond between HF molecules.


Option 1)

The electronegativity of fluorine is much higher than for other elements in the group.

Incorrect option
