Intermolecular Forces

The order of Intermolecule forces are as following (from lowest IMF to highest IMF),

  1. London Dispersion Forces (LDF) - for two non-polar molecules.
  2. Dipole-Dipole - for two polar molecules except Hydrogen bonding
  3. Hydrogen bonding - for polar molecules that have the following bonds, O-H, N-H, F-H
  4. Don't use until Solution Chemistry: Ion-dipole - an ion and a dipole molecule (e.g. water and sodium ion,Na1+)
  5. Ionic bonds - for compounds with ionic bonds (e.g. ionic compound)
  6. Metallic bond (same as ionic bond) - for metals bonding together or with themselves
