SUMMARY
The boiling points of substances are primarily determined by intermolecular forces, including Van der Waals forces and hydrogen bonding. In the comparisons provided, LiCl has a higher boiling point than HCl due to ionic bonding versus dipole-dipole interactions. NH3 exhibits a higher boiling point than PH3 because of stronger hydrogen bonding. Among noble gases, Xe has a higher boiling point than I2 due to greater Van der Waals forces resulting from larger atomic size and polarizability.
