Presentation Transcript

  1. Intermolecular Attractions Attractions Between Molecules • van der Waals forces • Two types: dispersion forces and dipole interactions • Dispersion forces • Weakest of all molecular interactions • Caused by movement of electrons • Occurs in the BrINClHOF’s

  2. Intermolecular AttractionsAttractions Between Molecules • 2nd van der Waals force • Dipole interactions • Occurs when polar molecules are attracted to one another • Partial charge (+) of one polar molecule is attracted to the opposite partial charge (-) of another molecule

  3. Chapter 16: Covalent Bonding-- Polar Bonds and Molecules -- Attractions Between Molecules • Hydrogen bonding • Hydrogen covalently bonded to a very electronegative atom is also weakly bonded to an unshared electron pair of another electronegative atom • Example: water
