How do you compare boiling points?

Several factors go into it. Usually, whatever has the weaker intermolecular forces will have the lower boiling point. For example, if comparing two molecules and one is capable of hydrogen bonding, that one will have the higher boiling point. If one is capable of dipole-dipole interactions and the other only has London dispersion then the former will have the higher boiling point. If two molecules being compared have the same possible intermolecular forces, the larger molecule has the higher boiling point.

Return to “Interionic and Intermolecular Forces (Ion-Ion, Ion-Dipole, Dipole-Dipole, Dipole-Induced Dipole, Dispersion/Induced Dipole-Induced Dipole/London Forces, Hydrogen Bonding)”
