Van Der Waal's forces are intermolecular forces named after Dutch scientist Johannes Diderik van der Waals. These forces are key in understanding the interactions between molecules and atoms. Additionally, Van Der Waal's forces can be referred to as London dispersion forces, London forces or instantaneous dipole-induced dipole forces. London dispersion forces arise from the interaction between an instantaneous dipole in one molecule and an induced dipole in another. Such interactions contribute to a host of important phenomena in nature, including the surface tension of water, the boiling point of alkanes and the viscosity of liquids. Van Der Waals forces are thus an important aspect of understanding the behavior of matter at a fundamental level.
