This web page is designed to help students of Organic Chemistry understand some concepts of stereochemistry. This is accomplished using the two types of exercises provided. One involves the classification of a given molecule as either chiral, achiral, or meso (click on the word to learn what it means). The other exercise involves the comparison of two molecules, and the determination of their relationship as enantiomers, diastereomers, constitutional isomers, non-isomers, or identical compounds.

The unique and hopefully helpful feature of these exercises is the ability to control the spatial orientation of each molecule. This is done using the Chemscape Chime^TM plug-in for Netscape Navigator^TM. If you can see the rotating molecule below, you already have the plug-in installed. Otherwise, click here to visit the Chime^TM plug-in site . Follow the installer instructions and then restart Netscape (or another frames-capable browser). You should then be able to see the rotating molecule below.
