(Despite this seemingly low value, the intermolecular forces in liquid water are among the strongest such forces known!) Which response includes all the molecules below that do not follow the octet rule? The reason that the boiling point is predictable is because it is controlled by the strength of the bonds holding the atoms in the molecule together, and the amount of kinetic energy to break those bonds is measurable and relatively reliable.
