Intermolecular Forces

What are the types of intermolecular forces?

Dispersion forces, Dipole-dipole forces, and Hydrogen bonding

Dispersion Forces

Attractions between non permanent dipoles of molecules. Dispersion forces are present in all molecules

Example: Van der waal forces and London forces

Dipole-dipole Forces

Attraction between dipoles of polar molecules

Hydrogen Bonding

Hydrogen attracted to lone pairs on N, O, and F

What intermolecular force(s) are present: HCl
