Answer

Electrons are randomly distributed, which results in formation of negative charge on one side of atom and positive charge in the place of voids.This charge formation results in forming instantaneous dipoles. The force between two dipoles is called the dispersion force.These forces are present in all elements.These forces depend on the size of electron cloud of an atom, so increased molar mass means a higher dispersion force.
