van der waals forces can best be described as the attractive or repulsive forces that are formed between oppositely charged ions in a crystal. during dipole - dipole interactions between molecules. when molecules move apart in the absence of other forces. by a random, short - lived redistribution of electrons.

Answer

Answer:

D. by a random, short - lived redistribution of electrons.

Brief Explanations:

Van der Waals forces include London dispersion forces which result from temporary electron redistributions creating instantaneous dipoles. Dipole - dipole interactions are a type of van der Waals force but not the best general description. Forces between oppositely charged ions are ionic bonds. And molecules moving apart without other forces is not related to van der Waals force formation.
