In comparison to most of the ionic and covalent bonds, these interactions do not arise from an electronic bond. In solids, these forces hold each other having lower melting points, and are relatively softer than the ones held by ionic or metallic bonds. In 1873, he first discovered the Van Der Waals bond while working on a theory on real gasses.Īccording to the Van Der Waals forces definition, they are comparatively weaker electrostatic forces that attract uncharged or neutral molecules towards each other in almost all organic liquids, gasses, and solids. Moreover, they are the weakest intermolecular forces, consisting of dipole-dipole and dispersion forces.Īs a segment of molecular physics, these forces came into existence from the name of a Dutch Scientist, Johannes Diderik Van Der Waals. These interactions include weak electrostatic forces lying in a close range within molecules lacking charges. In simple words, Van Der Waals Forces are those bonds that play the role of attracting both molecules and atoms.
