Respuesta :
Van der Waal forces are small dipole attractions between molecules caused by a temporary electron shift ,here, the option D is correct.
What are Van Der Waal forces?
Van der Waals forces exist among all kinds of atoms and molecules. The origin of this force stems from the instantaneous dipole-induced dipole interactions among adjacent polar atoms and molecules.
Among polar molecules, there are three components that contribute to the total forces: the induction force, the orientation force and the dispersion force.
The Van Der Waal forces that act between macroscopic bodies and surfaces in a solvent medium are relevant to the phenomena of protein adsorption.
