Key Concepts

London Dispersion Forces

London dispersion forces are weak intermolecular attractions that arise from temporary, instantaneous fluctuations in the electron distribution of atoms and molecules. These fluctuations create induced dipoles even in non-polar substances, leading to momentary attractions between neighboring particles. They are a type of van der Waals force and become more significant as the size and polarizability of the electron cloud increases.
