Chad's High School Chemistry Videos - 8.4 Electron Domain Geometry and Molecular Geometry | High School Chemistry

In this lesson, Chad covers VSEPR Theory (Valence Shell Electron Pair Repulsion) and Molecular Geometry. He begins by explaining how the different pairs of electrons around an atom (the electron domains) spread as far apart as possible in order to minimize repulsions leading to three basic electron domain geometries: linear (2 electron domains), trigonal planar (3 electron domains), and tetrahedral (4 electron domains). [Geometries for 5 and 6 domains are omitted here but are covered in Chad's General Chemistry playlist.] Chad then differentiates between the electron domain geometry and the molecular geometry and works through several examples showing how to determine the electron domain geometry and the molecular geometry from the Lewis structure. I've created a high school chemistry page that organizes all my videos by chapter - just an easier way for you to watch my YouTube videos.
