Van Der Waals Forces and London Dispersion Forces in Chemistry
Van der Waals forces, specifically London dispersion forces (LDF), represent a universal intermolecular mechanism arising from instantaneous fluctuations in electron distribution that induce temporary dipoles within nonpolar atoms and molecules. The strength of these forces is theoretically determined by molecular polarizability, which correlates directly with the number of electrons and atomic mass; greater polarizability facilitates stronger induced dipole interactions, thereby elevating physical properties such as boiling points and melting points in halogen series and hydrocarbon chains.
