Question - are london dispersion forces vanderwaal forces same

Answer 1

The forces acting between noble gas atoms are

A) van der Waals forces


Van der Waals’ force is the sum of all attractive and repulsive forces (except covalent force, hydrogen bond, electrostatic interaction) between molecules, two parts of a molecule. It includes:
force between two dipoles (Keesom force)
force between a permanent dipole and induced dipole (Debye force)
force between two instantaneously induced dipole (London dispersion force).

London dispersion force: it the force arises from two instantaneously induced dipole (or multipoles). It is weaker than van der Waals’ force.

Thus London dispersion force is one type of van der Waal force.
