Document Summary
These forces are considered weak, however, they tend to be very numerous and are determinants for the behavior of many substances. The van der waals forces, also known as van der waals interactions, are named in honor of the physicist johannes diderik van der waals, nobel prize in physics in. 1910, who was the first to take these forces into account. equations of state of gases. The van der waals forces are intermolecular forces. Currently, they are called van der waals forces to any force of attraction that occurs between molecules. But these attractive forces are produced between neutral molecules, that is, they have no charge, and they occur both in polar molecules and in non-polar molecules. Although the term van der waals forces is used generically to refer to the intermolecular attractive forces, three subtypes of these forces can be differentiated according to the characteristics of the attraction: London forces or instantaneous dipole-induced dipole (dispersion forces)
