Boiling Point and Polarity: A Close Relationship

Boiling point is a measure of the temperature at which a substance transitions from liquid to gas. Polarity is a measure of the separation of electric charge in a molecule. The two are closely related, as the higher the boiling point of a substance, the more polar it is. This is because polar molecules have stronger intermolecular forces, which require more energy to break. These intermolecular forces include dipole-dipole interactions, hydrogen bonding, and ion-dipole interactions.
