What types of intermolecular forces are collectively named van der waals forces after johannes van der waals?

Weak intermolecular forces

Explanation:

Weak, short-range electrostatic attractive forces between uncharged molecules are collectively named as Van der Waals forces, after the name of scientist who first discovered them "Johannes van der Waal".

They arise from interaction of electric dipole moments. These moments may be perminent or transient.
