Key Concepts

Intermolecular Forces

Intermolecular forces are the attractions between molecules, including London dispersion forces, dipole-dipole interactions, and hydrogen bonds. The strength of these forces determines many physical properties, such as boiling points. In cases where hydrogen bonding is present, it dominates and substantially raises the boiling point relative to molecules that rely mainly on weaker forces like dispersion forces.

Hydrogen Bonding

Hydrogen bonding is a special type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms such as oxygen, nitrogen, or fluorine. This bonding significantly increases the intermolecular attraction between molecules, resulting in higher boiling points compared to similar molecules that do not participate in hydrogen bonding.

Boiling Point Trends

Boiling point trends in a series of compounds are influenced predominantly by the type and strength of intermolecular forces rather than just molecular weight. Although a higher molecular weight can increase boiling points due to stronger dispersion forces, the presence of hydrogen bonding can lead to significantly higher boiling points because of the much stronger intermolecular attractions provided by these bonds.
