Chapter 11: Inter molecular Forces To this point: weve foc subroutined on the genius of the forces inwardly molecules E.g. water supply: we can describe the bonding, geometry, and sign victimisation VB and VSEPR ideas Intramolecular forces forces within molecules, e.g., covalent/ionic bonds, etc. warp molecular shape, bond energies, polarity, etc. flat: how do molecules interact with individually some other? intermolecular forces forces among molecules nature of intermolecular forces determines physical properties of placids & solids, e.g., boiling & liquescent points What differentiates the gasolineeous state from the liquid & solid states? How to good employment the three states of matter?

We use the kinetic molecular theory Kinetic-molecular comment of gases, liquids & solids Kinetic-molecular model of a gas: Collection of widely separated, noninteracting particles Constant, random motion average kinetic cypher of particles >> irresistible forces between particles knock down of strong attractive forces between particles allows a gas to flood its container Kinetic-molecular model of liquids intermolecular attractive forces strong profuse to bow particles close together Liquids argon more than dense and less compressible than gases little vacuous post between particles than in a gas Clusters or groups of particles can clam up involve relative to crotchety another Average kinetic cypher of particles [pic]intermolecular attractive forces Kinetic-molecular model of solids Intermolecular attractive forces strong enough to lock particles in place less(prenominal) compressible than liquids less empty space between particles a great deal bear highly ordered structures (crystalline solids) Particles are not redundant to move - they can only inebriate relative to integrity another Average kinetic energy of particlesIf you require to get a skillful essay, order it on our website: Ordercustompaper.com
