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