Dipole-Dipole Forces

• Dipole-Dipole Forces occur between polar covalent compounds.
• Dipole-Dipole Forces involves polar molecules that are usually permanent dipole molecules.
• Higher electronegativity differences between polar molecules ⟶ Stronger dipole-dipole force
• Larger molecular size of polar molecules ⟶ Stronger dipole-dipole force
• Examples of Dipole-Dipole Forces

  • CO (Carbon Monoxide)
  • HBr (Hydrogen Bromide)
  • SO2 (Sulfur Dioxide)
