The variation of the boiling points of the hydrogen halides is in the order

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?

Options

(a) There is strong hydrogen bonding between HFmolecules.
(b) The bond energy of HF molecules is greater than in other hydrogen halides
(c) The effect of nuclear shielding is much reduced in fluorine which polarises the Hf molecule.
(d) The electronegativity of fluorine is much higher than for other elements in the group

Correct Answer:

There is strong hydrogen bonding between HFmolecules.
