A quick explanation of the molecular geometry of SO3 including a description of the SO3 bond angles. • We can see that there are three atoms attached to the central Sulfur (S) atom and there are no upbonded electron pairs (also called a lone pair) on the Sulfur. Based on VSEPR Theory (Valence Shell Electron Pair Repulsion Theory) the SO3 molecular shape will be Trigonal Planar. This is because the Valence Shell Electron Pairs Repel each other. When they do so they are forced to the opposite side of the Sulfur atom giving SO3 a Trigonal Planar molecular shape. • The SO3 bond angles will be 120 degrees since it has a Trigonal Planar molecular geometry. • Helpful Resources: • • How to Draw Lewis Structures: • How to Draw Lewis Structures: Five Ea... • • Molecular Geometry and VSEPR Explained: • Molecular Geometry: Rules, Examples, ... • • Using the AXE Method for Molecular Geo: • Molecular Geometry, Bond Angle, Hybri... • • Molecular Geo App: https://phet.colorado.edu/sims/html/m... • Get more chemistry help at http://www.breslyn.org • Drawing/writing done in InkScape.
