Can someone please give an overview of van der Waals forces?

Van der Waals forces are also known as Dispersion/ induced dipole-induced dipole/ and London interactions. All of these terms describe intermolecular attractions that are always present and attractive. They arise due to fluctuating electron distributions, which results in fluctuating dipoles. These interactions are weak because they rely on temporary dipole movements in atoms.

Van Der Waals forces also consist of the potential energies of the dipole-dipole interactions of rotating polar molecules in the gas phase of the London interactions and the dipole-induced-dipole interactions.
