Chem 162 Dr. Nancy Marky Tues 9/4/07 Lecture #1 Intro, 11.1-11.2 Ch.11 States of Matter and Intermolecular Forces (Inter-particle) I. Electrostatic Attractions – Resulitng from changes in the electronic distribs these attractions are btw any combo of atoms, molecs + ions that DON’T result in covalent bond formation Intermolec vs Intramolec forces Ie. H-bonds ie. Covalent bonds The existence of condensed phases (liquids + solids) is largely due to these intermolec attractions II. Gas Phase 1. Macroscopic level a. gas expands to fill the space of its container b. no fixed vol, shape c. Ez to compress 2. Microscopic Level a. Particles are moving at large separation distances i. Therefore intermolec forces can be ignored III. Liquid Phase 1. Macro level a. Fixed vol b. No fixed shape c. Hard to compress bc of the bist btw particles 2. Micro Level a. Particles are close 2gether + intermolec forces are sig III. Solid Phase 1. Macro a. Fixed vol, shape b. Hard to compress i. dist btw parts is comp to the dist of those in liquid pahse…both
