Presentation Transcript

  1. Molecular shapes Chapter 9

  2. VSEPR model • Bonding pair = electrons in a bond = electron domain (~orbital/orbitals) • Non-bonding pair = electron domain (~orbital)

  3. Molecular geometry • Draw Lewis dot diagram • Determine number of electron domains  domain geometry • Non-bonding electron pairs must have maximum separation • Determine molecular geometry

  4. Molecular shape geometry

  5. Molecular shape geometry

  6. Molecular shape geometry

  7. Molecular shape geometry

  8. Bond angles • Lone pairs and double bonds take up more space • push other bonds closer together • Bond angles become smaller • e.x. H2O bond angle is about 104° • (instead of 109.5°)

  9. Bonding orbitals

  10. Sp3 Hybridized bonding orbitals sp3

  11. Sp2 hybridized bonding orbitals sp2

  12. Sp hybridized bonding orbitals

  13. σand πbonds
