Dispersion forces (answer) Explanation - Dispersion forces have many different names: London forces, Van der Waals forces, instantaneous dipoles. Dispersion forces involve the attraction between temporarily induced dipoles in nonpolar molecules (often disappear within an instant). This polarization can be induced either by a polar molecule or by the repulsion of negatively charged electron clouds in nonpolar molecules. As electrons move around their shells, electron density may randomly be distributed unevenly, creating a partially negative (?-) charge. The opposite side of the molecule then becomes partially positive (?+). The result is a temporary dipole. If this process occurs in two molecules that are close to one another, the two molecules will be attracted to each other, and will form a temporary, non-covalent bond.
