van der waals forces can best be described as the attractive or repulsive forces that are formed\no between oppositely charged ions in a crystal.\no during dipole - dipole interactions between molecules.\no when molecules move apart in the absence of other forces.\no by a random, short - lived redistribution of electrons.

Answer

Brief Explanations:

Van der Waals forces include London - dispersion forces which are caused by a random, short - lived redistribution of electrons (instantaneous dipoles) and also include dipole - dipole and dipole - induced dipole forces. Forces between oppositely charged ions are ionic bonds. Dipole - dipole interactions are part of van der Waals but London forces are also significant. Molecules moving apart in absence of other forces is not the description of van der Waals.

Answer:

by a random, short - lived redistribution of electrons.
