  1. VSEPR Theory Day 2: Molecular Geometry Objectives: 1. Identify the electron pair geometry and molecular geometry for covalently bonded molecules. 2. Determine the bond angles between atoms in a molecule.

  2. Draw the Lewis Dot Diagram of XeO2F2 and determine the electron pair geometry surrounding the Xe atom. What is a more accurate structure of this molecule?

  3. Electron Pair Geometry: Trig Planar Molecular Geometry: A = central atom X = attached atom E = attached e- pair

  4. Electron Pair Geometry: Trig Planar Molecular Geometry: A = central atom X = attached atom E = attached e- pair

  5. Electron Pair Geometry: Tetrahedral Molecular Geometry: A = central atom X = attached atom E = attached e- pair

  6. Electron Pair Geometry: Tetrahedral Molecular Geometry: A = central atom X = attached atom E = attached e- pair

  7. Electron Pair Geometry: Trig bipyramid Molecular Geometry: A = central atom X = attached atom E = attached e- pair Axialversus Equatorial

  8. Electron Pair Geometry: Trig bipyramid Molecular Geometry: A = central atom X = attached atom E = attached e- pair Axialversus Equatorial

  9. Electron Pair Geometry: Octahedral Molecular Geometry: A = central atom X = attached atom E = attached e- pair

  10. Electron Pair Geometry: Octahedral Molecular Geometry: A = central atom X = attached atom E = attached e- pair

  11. Practice: 1. Which of the following molecules has tetrahedral electron pairs, but a bent molecular geometry. CO2ClF21+ BrCl21- 2. Describe the approximate bond angle you would expect between the three atoms in each of the previous examples.
