Attractions Between Molecules

Molecules can be attracted to each other due to a variety of intermolecular forces.

van der Waals forces.

The weakest types of attractions between moleculesdispersion forces and dipole interaction are called van der Waals forces.

Dispersion forces

The weakest of all molecular interactions, called dispersion forces or London dispersion forces, are caused by the motion of electrons.

Nonpolar molecules

Hydrogen is a nonpolar molecule, and the electrons are evenly distributed. However, electrons shift around in molecules.

Temporary forces

A weak electrostatic attraction forms between partial positive and partial negative ends of the temporary dipoles. The attraction breaks up when electrons move again.

are intermolecular attractions between oppositely charged regions of polar molecules
