9.1 VSEPR Theory and Molecular Shapes | General Chemistry

Chad provides a comprehensive lesson on VSEPR Theory and Molecular Geometry. The five fundamental Electron Domain Geometries (EDGs) including the bond angles are first covered: Linear, Trigonal Planar, Tetrahedral, Trigonal Bipyramidal, and Octahedral. Then the corresponding Molecular Geometries are covered being grouped by the number of electron domains with examples of each being presented. This includes the following: 2 Electron Domains: Linear 3 Electron Domains: Trigonal Planar & Bent 4 Electron Domains: Tetrahedral, Trigonal Pyramidal, & Bent 5 Electron Domains: Trigonal Bipyramidal, See-saw (aka Sawhorse), T-shaped, & Linear 6 Electron Domains: Octahedral, Square Pyramidal, & Square Planar The effect of lone pairs and pi bonds reducing bond angles is also covered. I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page.
