Question 3 of 10 Why are Van der Waals forces important?
A. They are the strongest type of intermolecular force that can act on
polar and nonpolar molecules.
B. They are the primary intermolecular attractive forces that act
between nonpolar molecules.
O c. They determine how strong dipole moments will be in polar
covalent molecules.
O D. They are the strongest type of intramolecular force that can act
between atoms.
