weakest attractive force between two molecules

Answer 1

The weakest attractive force between two molecules is the London dispersion force, also known as the van der Waals force. This force arises due to temporary fluctuations in the electron distribution within molecules, leading to the formation of temporary dipoles. These temporary dipoles induce a similar temporary dipole in neighboring molecules, creating an attractive force between them. The London dispersion force is the weakest of the intermolecular forces.
