Intermolecular Interactions

Definition

Intermolecular interactions are forces of attraction between molecules that determine their physical properties and behavior. These interactions include hydrogen bonding, dipole-dipole interactions, London dispersion forces, and ion-dipole interactions.

Related terms

Hydrogen Bonding: This term refers to the strong intermolecular attraction between a hydrogen atom bonded to an electronegative atom (such as oxygen or nitrogen) and another electronegative atom.

Dipole-Dipole Interactions:

This term refers to the attractive forces between the positive end of one polar molecule and the negative end of another polar molecule.

London Dispersion Forces: This term refers to the temporary attractions that occur when electron distribution within a molecule is momentarily uneven, creating temporary dipoles.
