Which intermolecular forces are called as long range forces?

Which intermolecular forces are called as long range forces? Correct Answer Van der Waals forces

Long range forces are the forces that do not need contact between the objects to exist. Van der Waal forces are called long range forces, because they act outside the 3 angstroms and are attractive in nature. They are responsible for surface tension, viscosity, friction and differences between the actions of gases.
