Question:

HF has highest boiling point among hydrogen halides, because it has:

strongest hydrogen boding

lowest dissociation enthalpy

strongest van der Waal's interactions

lowest ionic character

Solution:

Correct option is A. strongest hydrogen boding
HF has the highest boiling point among hydrogen halides because it has the strongest hydrogen bonding.
In HF, there is a high electronegativity difference between H and F, thus they form strong intermolecular hydrogen bonding.
