Brown, LeMay AP Chemistry
2 11.1: Intermolecular Forces (IMF) Intermolecular forces (IMF) are the forces that exist
between the molecules of a substance
IMF are weaker than intramolecular forces (forces within molecules like covalent, metallic, ionic bonds)
Inter means

3 11.1: Intermolecular Forces (IMF)
Think about the states of matter. 1. With your table discuss the strength of the
intermolecular forces in a state of matter. Rank the strength from weakest to strongest.
2. Once you have your ranking, Use your understanding of the different states of matter to support why your ranking is correct.

Gases < Liquids < Solids
5 11.1: Intermolecular Forces (IMF)
Boiling Point & Melting Point and IMF strength:
Do Intermolecular Forces impact boiling and melting points of a substance? Explain your thoughts.
6 11.2: Types of IMF

20 London Dispersion Forces • Exists between all molecules
– Polar molecules experience dipole-dipole interactions along with dispersion forces (dipserions in polar molecules commonly contribute more to intermolecular attraction)
• Comparing relative strengths of IMF in two substances: – IF MW are similar dispersion forces are
