You just calculated that the heat of fusion for chloromethane is 6400 j/mol. the heat of fusion for hydrogen is 120 j/mol. which of the following account for this difference? check all that apply. view available hint(s) check all that apply. hydrogen molecules can pack more closely than chloromethane molecules. chloromethane can absorb more energy at the same temperature. chloromethane experiences dipole-dipole interactions. hydrogen has stronger intermolecular forces than chloromethane. chloromethane has a higher molar mass than hydrogen.
