Experiment 9: VSEPR General Chemistry I and II Lab Manual Dakota State University Page 103 of 232 Experiment 9: VSEPR Purpose: To use the Valence Shell Electron Pair Repulsion Theory to predict molecular shapes Pink: Not just a color, but also a singer Background: See “Using HyperChem” Introduction: Sure, Quantum Theory is powerful, but sometimes, simple is better. Simple implies more insightful, more intuitive, easier to utilize, and sometimes just as good as more difficult theory. One such simple, insightful theory is the Valence Shell Electron Pair Repulsion Theory (VSEPR, often pronounced as "vesper"). VSEPR is a simple model that was developed to predict the shape of covalently bonded compounds. It turned out to be exactly "on the mark". Nowadays, we can use quantum theory to predict the same thing, by forming "bonding orbitals", which are solutions to Schroedinger's equation created by the overlap of orbitals from each atom involved in the bond. The odd thing,
