Intermolecular forces

What are the different types of Intermolecular forces/forces? How do you identify them?

Ion- ion forces > ion-dipole forces > dipole-dipole > dipole - induced dipole > induced dipole -induced dipole. And then hydrogen bonds are basically just really strong dipole-dipole forces

The three major types of intermolecular interactions are London dispersion forces, dipole–dipole interactions and hydrogen bonds

You can identify the type of intermolecular forces by looking at the dipole moments of the molecules.

To add on:
London dispersion forces are the weakest of all of these, and are seen in any type of molecule.
dipole-dipole interactions are the next strongest interactions and occur between polar molecules, which is determined by a molecule's shape.
Hydrogen bonding is the strongest, and occurs when a positive H atom is attracted to the lone pairs on N, O, or F atoms because of their high electronegativity.

Hydrogen bonding: H bonded to FON with a LP. Only H bonded to FON will be attracted to other regions with H bonded to FON
Ions can have: ion-dipole, ion-ion
anything with dipole moments will have: dipole-dipole
molecule w dipole + molecule w no dipole = dipole-induced-dipole
All Molecules (polar and nonpolar) : LDF/induced dipole-induced dipole
