A temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.


Also referred to as London Dispersion force, the induced dipole-induced dipole force is a weak intermolecular interaction that occurs between any two molecules that are close together (even polar molecules).

Because electrons are constantly moving around in the electron cloud, a temporary (instantaneous) dipole can arise if the electrons are unevenly distributed around the molecule.

This temporary dipole can disturb the electrons in another molecule, inducing a dipole to form. The temporary dipoles form an electrostatic interaction – London dispersion force.
