Intermolecular forces are forces that exist between atoms. These include London Dispersion, Van der Waals, and Hydrogen
London Dispersion: also known as Van der Waals forces.
Van der Waals: A weak attractive force between atoms or nonpolar molecules.
Hydrogen Bonding: When a hydrogen atom is attracted to another atom with a slightly negative or positive
charge, resulting in a crystal lattice.
Dipole Dipole: A force in which one atom in a compound has a slighty negative charge due to the pulling
in of electrons from the other atoms in the same compound.

Intramolecular forces are forces that exist between molecules. These forces include Ionic, Covalent, Multivalent, etc.
Here are some definitions of the following:
Ionic Bonding: An intramolecular bond between a meetal and a non metal.
Molecular Bonding: An intramolecular bond between two non metals.
Covalent Bonding: An intramolecular bond where two atoms share valence electrons.
