What are main characteristics of Van der Waals forces?

1) They are weaker than normal covalent and ionic bonds. 2) Van der Waals forces are additive and cannot be saturated. 3) They have no directional characteristic. 4) They are all short-range forces and hence only interactions between the nearest particles need to be considered (instead of all the particles). Van der Waals attraction is greater if the molecules are closer. 5) Van der Waals forces are independent of temperature except for dipole – dipole interactions.
