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

HF

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

Options

Alowest dissociation enthalpy
Bstrongest van der Waals’ interactions
Cstrongest hydrogen bonding
Dlowest ionic character

Correct answer

C. strongest hydrogen bonding

Step-by-step solution

Boiling point is directly proportional to intermolecular Forces. Since Fluorine is highly electronegative element it forms hydrogen bonding. Because of $H -$ bonding $HF$ has high boiling point.
HF has highest boiling point among hydrogen halides, because it has:
