Boiling Point

[KNguyen_1I]

When considering boiling point, what are the rankings of the intermolecular forces (from weakest to strongest) we should consider to determine highest boiling point?

[205296774]

The rankings for intermolecular forces are as follows:

london dispersion < dipole-dipole < H-bond < ionic bond

It can therefore be determined that ionic bonds will have the highest boiling point because, as the strongest bonds, they require the greatest amount of energy (heat in this case) to be broken and subsequently change states.

Hope this helps!

Concept: The stronger the bond, the higher the boiling point.

From highest to lowest boiling point:

ion - ion
ion - dipole
hydrogen bond
dipole - dipole
induced dipole - dipole
induced dipole - induced dipole

The highest boiling point would be of the strongest molecule. Molecule's strength is measured by its intermolecular forces.
Ionic bonded molecules would have the highest boiling point.
London Dispersion forces would be the easiest to break resulting in lowest boiling points.

Ion-ion bonds have the highest boiling points whereas london force have the lowest boiling points.

If it has more surface area, will the boiling point be higher?

[Tiffany Vo 3G]

If it has more surface area, will the boiling point be higher?

The boiling point should be higher if the molecule has more surface area.
