On the other hand, intramolecular forces that is, forces which exist within the same . 16 kJ/mol vs. 431 kJ/mol for HCl). Polarity increases the attractive forces between the molecules; a polar compound should have a relatively higher boiling point. 2 is more polar and thus must have stronger binding forces. d. That CH 2Cl 2 has a higher boiling point proves that is has stronger intermolecular . Increased attraction between molecules = more energy required to break them to move from liquid to gas state = higher temperature needed. and hclo is a polar molecules. This option allows users to search by Publication, Volume and Page Selecting this option will search the current publication in context. Only dipole-dipole and hydrogen bonding forces are present.
