Chapter 11 A. Intermolecular Forces: 1. attractive forces between molecules 2. see a lot with condensed phases of matter i. Phases of matter- Solid Liquid Gas 1. energy is needed to change phase and to overcome intermolecular forces Boiling Point: molecules have enough energy to start at liquid phase and go to gas. H20- high boiling point strong intermolecular force C3H8- gas @ room temp, low boiling point have weak intermolecular forces Gases will always have weak intermolecular forces!!! Low boiling point= weak intermolecular forces High boiling point= strong intermolecular forces Intermolecular forces- are electrostatic attractions between ions. may be a partial charge may have temporary charges Strength of intermolecular forces depends on: size or magnitude of charge distance between the charge species Types of forces: 1. Dispersion Forces (London Forces) a. weakest force b. Involves transient (instantaneous) dipoles. (= have a negative and positive side. not equal on each side) i.
