VSEPR and possible shapes
Molecular Shapes: VSEPR
Overview
This module is an introduction to using VSEPR to predict molecular shape based on Lewis structures. It is limited to steric numbers of 6 or less.
How to go from Lewis structure to Geometry
The YouTube video is from UT Austin.
This module is limited to a steric number of 6 or less. The specific examples in the mini-lecture are PCl3, XeF4, and CO2.
We have to talk about the possible geometries before we can predict the shape of a molecule based on its Lewis structure.
First, we step into geometry and bond angles with Valence Shell Electron Pair Repulsion and the possible shapes we encounter in general chemistry.
Next, we explore how to go from a Lewis Structure to a VSEPR geometry in the mini-lecture.
