Van Der Waals' Forces - Definition Of Van Der Waals' Forces
Van der Waals' forces are a group of relatively weak intermolecular interactions which generally result when a molecule or group of molecules become polarized into a magnetic dipole. This happens most often due to uneven or shifting distributions within the electron cloud of the atoms. These sorts ... Read Article
