Intermolecular Forces

These are weak attractions such as hydrogen bonds that keep molecultes together.

Sublayer Name Examples
Upper London Dispersion Forces Protein folding
Mid Dipole–Dipole Forces Hydrogen Bonding
Lower Ion–Dipole Forces boiling poin

London Dispersion Forces

This is the weakest type, but very important in nonpolar substances (e.g., liquid O₂, noble gases).

Dipole–Dipole Forces

Between molecules that have permanent dipoles (polar molecules). Example: HCl–HCl

An example is hydrogen bonds.

Ion-Dipole

This is between an ion and a polar molecule.

Example: Na⁺ ions interacting with water molecules in saltwater.
