VSEPR Theory: Introduction

This is an introduction to the basics of VSEPR Theory. VSEPR theory is a set of rules for how to look at a Lewis structure and determine the three dimensional (3D) shape of a molecule. The shapes have to do with the location of bonds and lone electrons pairs. In this video, we'll look at the following shapes: linear, trigonal planar, bent, tetrahedral, and trigonal bipyramidal

VSEPR Theory Practice Problems

Lots and lots of practice problems for VSEPR theory. We will look at how to take a Lewis structure and determine what the 3D shape of the molecule will be. Here are the shapes that we will talk about: tetrahedral, trigonal pyramidal, bent, trigonal planar, linear. We will also talk about angles in degrees: 109.5º, 107º, 105º, 120º, 180º and 116º and amounts that are less.
