The variation of the boiling points of the hydrogen halides is in the order `HFgtHIgtHBrgtHCl`.
What explains the higher boiling point of hydrogen fluoride?

Options

A. The bond energy of HF molecules is greater than in other hydrogen halides
B. the effect of nuclear shielding is much reduced in fluorine which polarizes the HF molecule
C. The electro negativity of fluorine is much higher than for other elements in the group
D. there is strong hydrogen bonding between HF molecules

Answer

D

Explanation

Boiling point of HF is maximum because HF molecules associated by hydrogen bond.

Bpt. `HF gt HIgtHBrgtHCl`
