The meaning of VAN DER WAALS FORCES is the relatively weak attractive forces that act on neutral atoms and molecules and that arise because of the electric polarization induced in each of the particles by the presence of other particles.
Van der Waals forces are the weakestintermolecular forces. Their strength typically ranges from 0.4 kilojoules per mole (kJ/mol) to 4 kJ/mol and acts over distances of less than 0.6 nanometers (nm). When the distance is less than 0.4 nm, the net effect of the forces is repulsive as ele...
Van der Waals forces are the consequence of intermolecular polarities, due to the structure of a single molecule, may reveal Van der Waals forces that are the improved result of a few various types of polar contributions.

Van der Waals forcesare well known to function as the primary interparticulate interaction in dry powder beds prepared by ordered mixing (Dickhoff, 2006). Specifically, small particles in the range intended for pulmonary delivery (<5 µm) exhibit increasedvan der Waals interactionswhich dominate...
Van der Waals forces, also known as van der Waals bonds or van der Waals interaction, are weak intermolecular interactions observed in condensed phases like solid and liquid. They are responsible for the bulk properties of substances, like the boiling and melting points. Van der Waals bonds are...
