(The strength of these attractive forces is directly proportional to the charge separation that occurs in the molecules. Ionic bonds involve oppositely charged ions, which have the greatest charge separation. Nonpolar molecules, which form momentary dipole moments, have dispersion forces and the smallest separation of charge. Ionic bonds are the strongest of these attractive forces, and dispersion forces are the weakest.) hottest-coldest Identify each of the compounds as ionic or mol...
