What intermolecular force is responsible for the fact that ice is less dense than liquid water? Methanol is a polar molecule (1.69 D), and so it exhibits all three of the van der Waals forces: Keesom forces (dipole-dipole attraction), Debye forces (induced attraction) and London dispersion forces (which all molecules exhibit). Expert Answer . Intermolecular forces are generally much weaker than covalent bonds. The predominant intermolecular force of CH3Cl, chloromethane, is the covalent bonds which binds all of the atoms with the carbon being in the center.
