The correct answer is "there are many Van der Waals forces acting between molecules of sulfur dioxide"
Explanation:
Van Der Waals forces are considered one of the weakest forces, however, since they exist in multiple levels, they have a major influence in molecules behavior. Van Der Waals forces are intermolecular interactions that emerge from the electrons movement in the atoms and the place that the electrons have in a given moment. In the case of sulfur dioxide, the atoms of sulfur and oxygen have Van Der Waals forces within them and among them. Particularly, the electrons within the individual atoms, as well as the electrons able to interact among the sulfur dioxide molecules, have all Van Der Waals forces.
Dipole-dipole attraction is a type of vander waals forces found in the molecules of sulfur dioxide.
Vander waals forces are weak attractions joining non-polar and polar molecules together. They are of two types:
London dispersion forces which are weak attractions found between non-polar molecules.
Dipole-Dipole attraction are the forces of attraction which exists between polar molecules. Such molecules have permanent dipoles. This implies that the positive pole of one molecule attracts the negative pole of another. This is what happens between the oxygen and sulfur molecules.
