Chapter 10 notes Claire Rafson 10.1-10.2 Intermolecular forces- occur b/w not in molecules. From solid to liquid to gas molecules remain in tact Forces: Dipole-dipole forces are forces that act between polar molecules Hydrogen bonding- strong form of dipole dipole with H and NOF London Dispersion- Present in all but ionic . noble gas and nonpolar and Polar. Big atom with a lot electrons LD can be stronger than dipole dipole Higher IMF = higher: surface tension, boiling/meltin point. Lower: vapor pressure Capillary action- polar liquids typically exhibit it 10.3- crystalline solids- highly regular arrangement of their components ionic and molecular amorphous solids- considerable disorder 10.5- Network atomic Solids- giant molecule Strong covalent bonds Silica- SiO2
