London’s dispersion forces can be defined as a temporary attractive force due to the formation of temporary dipoles in a nonpolar molecule. When the electrons in two adjacent atoms are displaced in such a way that atoms get some temporary dipoles, they attract each other through the London dispersion force.
London dispersion forces can explain how liquids and solids form in molecules with no permanent dipole moment. "Dispersion" means the way things are distributed or spread out. Because the electrons move around a lot, sometimes they may move in a way that creates a temporary dipole moment.
London dispersion forces (LDF, also known as dispersion forces, London forces, instantaneous dipole–induced dipole forces, fluctuating induced dipole bonds or loosely as van der Waals forces) are a type of intermolecular force acting between atoms and molecules that are normally electrically symmetric; that is, the electrons are ...
The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction.
Sep 1, 2019 · London dispersion force is a weak intermolecular force between two atoms or molecules in close proximity to each other. The force is a quantum force generated by electron repulsion between the electron clouds of two atoms or molecules as they approach each other.
London dispersion forces result from the coulombic interactions between instantaneous dipoles. Dispersion forces are present between all molecules (and atoms) and are typically greater for heavier, more polarizable molecules and molecules with larger surface areas. Created by Sal Khan.

Nov 21, 2023 · London dispersion forces are the weakest form of intermolecular forces that exist as the strongest forces between non-polar particles in a substance. What Are London Dispersion Forces?...
Van der Waals forces include London dispersion forces (discussed below), dipole-dipole forces, and ion-dipole. The strongest force of these is ion-dipole followed by dipole-dipole. London dispersion forces are the weakest force. All molecules experience London dispersion forces.
Sep 4, 2023 · The London dispersion force is a transitory attractive force that develops when electrons in two neighboring atoms retain positions that lead the atoms to form momentary dipoles. This force is also known as an induced dipole-induced dipole attraction.
Dipole-dipole, London dispersion (also known as Van der Waals) interactions, hydrogen bonding, and ionic bonds are the main types of intermolecular interactions responsible for the physical properties of compounds.
