VSEPR stands for Valence Shell Electron Pair Repulsion. It is a theory which allows the user to predict the shapes of simple polyatomic molecules by applying a set of straight forward rules.
 
This computer course is designed to teach the user the VSEPR rules. Once the user is familiar with the rules a set of worked examples are available to show how they are applied to unfamiliar molecules. Then there is a set of problems in which the user must determine the geometry of a series of molecules which will be randomly selected by the computer.
 
Once the user has completed this course they are advised to work their way through the Symmetry Practical which is also on the Virtual Laboratory site.
