2. Boiling point indicates the strength of intermolecular interactions. Given the boiling points in parentheses, rank the following molecules in order from strongest to weakest intermolecular interaction: methane (CH4,164C), formaldehyde (CH2O,21C), methanol (CH3OH,65C), and calcium chloride (CaCl2,782C). Also, indicate the type of interaction: ionic bonds, London dispersion forces, dipole-dipole interaction, and H-bonds
