From Gen Chem to Org Chem, Pt. 7 - Lewis Structures – Master Organic Chemistry
Steps of VSEPR model: 1. Draw the Lewis Dot Diagram structure 2. Determine the number of electron groups around the central atom 3. Assign each molecule a formula ( A=central atom, X=bonded atom, E=nonbonding electrons, and m/n are integers) 4. Identify the types of bonds, number of bonds and lone pair of electrons. 4. According to the bonds and lone electron pairs, predict deviations from ideal bond angles. 5. Describe the molecular geometry.
