Understand how to determine the shape or geometry of a molecule using the VSEPR rules, for valence shell electron pair repulsion.

In this tutorial, take a look at diagrams of the VSEPR shapes, and examine bond angles for each structure. [15:06]

This is an introduction to the basics of VSEPR Theory. In this video, learn about the following shapes: linear, trigonal planar, bent, tetrahedral, and trigonal bipyramidal.

Learn how to take a Lewis structure and determine what the 3D shape the molecule will be using the VSEPR theory. [14:24]
