Intermolecular forces: weakest London dispersion forces (Van der Waals) everything has these stronger in larger molecules or molecules with large surface area Dipole-Dipole forces weak attractions between polar molecules when there is one electronegative element and nothing to balance it out ex. HCl, SO2, CH3Cl, NH3, H2O, H2S, CH2O, CH3NH2 stronger with more electro negativity Hydrogen bonding found when a hydrogen is attached to a nitrogen, oxygen, or fluorine ex. H2O, NH3, HF, CH3OH, DNA base pairs strongest if H-F, then H-O, then H-N Ion-Dipole forces the larger the ion, the stronger the force ex. NaCl, Na2O stronger with higher charge strongest viscosity - resistance to flow increases with intermolecular forces decreases with tempertaure surface tension increases with intermolecular forces evaporation increases with intermolecular forces H vap, heat to vaporize 1 mol of liquid + H cond, heat to condense 1 mol of liquid - vapor pressure how gas pressure changes in a closed container decreases with intermolecular forces boiling point when Pvap = P external normal B.P is temp when liquid boils at Pvap = 1 atm can be lowered by reducing P external increases with intermolecular forces freezing point when crystal lattice forms normal F.P is temp when liquid freezes at Pcond = 1 atm H fusion = + heat added to solid to form liquid H crystallization = - heat removed from liquid to form solid solids properties dependent on: nature of particles forces or bonding between them geomatrical packing ionic-ionic particles-ionic bond attraction-hard and brittle-NaCl metallic-atoms of electropositive elements-metallic bonds-shiny and malleable-Cu, Fe, Ti covalent-atoms of electronegative elements-covalent bonds-very hard- C(diamond), SiO2 molecular-molecules-variable hardness-H2O, CO2, I2 phase diagrams solidm liquid gas triple point- when all three states are in equilibrium critical point- temp and pressure when the liquid and gas phases are not detectable pressure (atm) temp (C) Made with nCreator - tiplanet.org
