Question

Name two intermolecular forces that exist between $HF$ molecules in liquid state.

Answer 1

$\text{Intermolecular forces in}HF:$

Two intermolecular forces that exist between $HF$ molecules in liquid state are Hydrogen bonding and dipole-dipole interaction.


$H$-bonding forms when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons.

Dipole-dipole interaction forms when two dipolar molecules interact with each other through space.
