What is Van der Waals Forces?
Weak intermolecular forces including London dispersion forces, dipole-dipole interactions, and dipole-induced dipole interactions. Named after Johannes Diderik van der Waals. These forces are responsible for the condensation of gases, properties of liquids, and physical adsorption.

Weak intermolecular forces including London dispersion forces, dipole-dipole interactions, and dipole-induced dipole interactions. Named after Johannes Diderik van der Waals. These forces are responsible for the condensation of gases, properties of liquids, and physical adsorption.
Van der Waals forces explain why non-polar substances like noble gases can be liquefied at low temperatures. They are exploited in non-covalent drug-receptor interactions and molecular recognition. Gecko adhesion to surfaces is a remarkable biological example of van der Waals forces in action.
Van der Waals forces are fundamental interactions. Molecules held together primarily by weak van der Waals forces tend to be volatile, which can create flammability and inhalation hazards.
The formula or notation for Van der Waals Forces is: Fvdw = London + dipole-dipole + H-bond; E ∝ 1/r⁶
