Due to strong H-bonding in HF molecule, boiling point is highest for HF.
HF>HI>HBr>HCl
The variation of the boiling points of the hydrogen halides is in the order HF>HI>HBr>HCl . Which of the following option explains the higher boiling point of hydrogen fluoride?
Held on 30 Apr 2015 · Verified 9 Jul 2026.
The electronegativity of fluorine is much higher than for other elements in the group.
There is strong hydrogen bonding between HF molecules.
The bond energy of HF molecules is greater than in other hydrogen halides.
The effect of nuclear shielding is much reduced in fluorine which polarizes the HF molecule.
