Intermolecular forces are weaker than intramolecular forces but still very important. The two intermolecular forces we are talking about in this video include dipole-dipole and ion-dipole. Dipole-Dipole Forces. A dipole is a molecule that has both positive and negative regions.
Intramolecular forces are the forces that hold atoms together within a molecule. Intermolecular forces are forces that exist between molecules. Types of intramolecular forces of attraction. Ionic bond: This bond is formed by the complete transfer of valence electron(s) between atoms.
