The boiling point is determined by the strength of intermolecular interaction (type of intermolecular forces present). Carbon tetrachloride is a compound having the molecular formula CCl4. Dipoles are stronger than London Forces alone, so polar molecules tend to have stronger intermolecular forces than nonpolar molecules of a similar size and polarity. Best Answer: If you mean intramolecular forces (because intermolecular forces occur between two different molecules), then there is a net electronic dipole movement in the direction of the three chlorines (since they are are more electronegative than nitrogen and the electrons want to spend more time around them). A hydrogen atom attached to a relatively electronegative atom is a hydrogen bond donor. Co L IL IL 34 L 2. The atoms in a molecule are bonded together by intermolecular forces.
