3. Unit 3: Kinetic Molecular Theory and States of Matter Intermolecular Forces and Liquids, Day 1

4. Intermolecular Forces and Liquids, Day 1 Gases vs. Liquids Gases and liquids can both be referred to as “fluids”, or as exhibiting “fluidic behavior”, but they are obviously VERY different. What are the primary differences between the two states of matter? Think on the atomic scale and the macro- scale.

5. Intermolecular Forces and Liquids, Day 1 Polar molecules: H2, HF and LiF. May the truth set you free … Dipole-Dipole Interactions: When one polar molecule is near another polar molecule, they are attracted to one another! This is called a dipole-dipole interaction. Effect on heat of vaporization (∆vapH), boiling point, and dissolving ability

6. Intermolecular Forces and Liquids, Day 1 DISSOLVING AND MIXING: http://www.youtube.com/watch?v=EBfGcTAJF4o 1. Interactions of Ions and Polar Molecules: (+) end is attracted to anion and (-) end is attracted to cation. The ionic compound becomes _______________. Factors effecting ion-dipole interactions: Rank Cs+ Mg2+ and Na+ by increasing attraction to polar molec.
