How is the Boiling Point Determined?

Generally speaking, the boiling point of a molecule is the temperature at which a liquid will begin to boil. It is a predictable phenomenon, because of the way it is controlled by the strength of the bonds between atoms. However, this is not the only way the boiling point is determined. Other factors include London dispersion forces, dipole induced dipole forces, and disruption forces within the molecules. The strength of the atom bond and the size of the molecule are also important.

A molecule is considered non-polar if it does not contain ionic bonds. When there are no ionic bonds, there are no hydrogen bonds between the atoms. This causes the molecules to vibrate more, and increases their kinetic energy. Because of this, it becomes possible for molecules to bump into each other. If there are multiple molecules that are vibrating, there is a greater chance that they will come into contact, which increases their kinetic energy. Therefore, the boiling point of a molecule may be higher than that of a neutral molecule.

The boiling point of a molecule is determined by a combination of its molecular geometry, its atomic structure, and the amount of kinetic energy available to break its bonds. In addition, the strength of its atom bonds and its ionic bond are also factors in determining its boiling point. For example, methane has a significantly larger molecular area than other hydrides, and so its boiling point is higher.
