Explain in terms of intermolecular forces the following: why nai has a higher melting point than i2 because nai can form hydrogen bonds, and i2 cannot. because nai is an ionic compound, and the ion-ion attractions are much stronger than the dispersion forces between the i2 molecules. because nai is a solid, and i2 is a liquid. because nai is soluble in water, and i2 is not.
