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 electronegativity of fluorine is much higher than for other elements in the group
B. There is strong hydrogen bonding between HF molecules
C. The bond energy of HF molecules is greater than in other hydrogen halides
D. The effet of nuclear shielding is much reduced in florine which polarises the HF molecule

Answer

B

Explanation

Since, there is a strong bonding between `HF` molecules . Hence, boiling point is highest for `HF`.
`HF gt HI gt HBr ge HI`
