  1. Intermolecular Forces Ch. 7 – Chemical Bonding

  2. A. Definition of IMF • Attractive forces between molecules. • Much weaker than chemical bonds within molecules. • a.k.a. van der Waals forces

  3. B. Types of IMF

  4. B. Types of IMF • London Dispersion Forces View animation online.

  5. + - B. Types of IMF • Dipole-Dipole Forces View animation online.

  6. B. Types of IMF • Hydrogen Bonding

  7. C. Determining IMF • NCl3 • polar = dispersion, dipole-dipole • CH4 • nonpolar = dispersion • HF • H-F bond = dispersion, dipole-dipole, hydrogen bonding
