Which forces involve nonpolar molecules?
Elanso [62]
The answer is London dispersin forces and dipole-induced dipole forces.

The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction. This force is found in any compound and is the weakest atraction force between atoms or molecules.

Those temporay dipoles are not like the dipoles that form the polar molecules, because the polar molecules are the result of permanent dipoles.
