Bonding and Molecular Shape – 06 Intermolecular Forces Aim: How is a Lewis Structure used to determine the shape of a molecule? Do Now: How are polyatomic ions drawn using Lewis structures? Lewis Structures and Molecular Geometry Based on the Lewis Structure of a molecule, you can determine its 3-dimensional shape. VSPER Theory The Valence Shell Electron Pair Repulsion Theory provides guidelines

Unformatted text preview: to determine the molecular geometry of a small molecule. 1. Shape is based on spacing shared and unshared pairs of electrons as far apart as possible. 2. Double and triple bonds are equivalent to a single bond (VSEPR theory only) Practice: Draw the Lewis Structure and predict the geometry. 1. CS 2 2. H 2 S 3. SiH 4 4. SCl 6 5. PF 3...
