1 I. Intermolecular Forces
Ch Liquids & Solids I. Intermolecular Forces

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
