Of the following substances, only _______has london dispersion forces as its only intermolecular force A)NH3 B)HCl C)CH4 D)H2S E)CH3OH *I know all molecular substances have this force (polar or nonpolar) but nonpolar molecules only have this force and nothing else. How do I know if these molecules are polar or nonpolar?
