This video tutorial by Manal, a Lead Tutor at the UNT Learning Center, covers intramolecular and intermolecular forces. It explains covalent, ionic, and metallic bonds as intramolecular forces, and van der Waals, dipole-dipole, hydrogen bonding, and ion-dipole as intermolecular forces. The video defines each force, provides visual examples, and compares their strengths. Intramolecular forces are generally stronger than intermolecular forces, with ion-dipole being the strongest among the latter. The tutorial concludes with a summary of the discussed forces.
