Collection of Chiral Drug, Pesticide, and Fragrance Molecular Models William F. Coleman
The article by Mannschreck, Kiessewetter, and von Angerer on the differential interactions between enantiomers and biological receptors (1) is the source for this month's Featured Molecules. Included in the molecule collection are all of the molecules described in the paper. In many instances we have included structures of multiple optical isomers of the same molecule so that students can not only see the forms that are active, but those that are less active, inactive, or act in an undesirable manner. These molecules will serve as good practice in determining optical configurations, and will also introduce additional forms of isomerism that students may be less familiar with than they are with R and S. Since multiple enantiomers and diastereomers are provided, students may use these molecules, together with an appropriate computational package, to verify that enantiomers have the same energy while diastereomers do not. The tuberculosis drug ethambutol provides an interesting case as both nitrogen atoms are also chiral as well as the two chiral carbon atoms. A calculation on a given structure will include the effect of that nitrogen chirality, although nitrogen inversion is expected to be quite rapid in this molecule. The conformations for the ethambutol molecules that are included here consider all four chiral atoms and are of the form (CNNC). A reasonable computational exercise would be to find the transition state for nitrogen inversion and the barrier height for that process. The supplemental material that is included with the featured article (1) includes a number of molecules that we will add to the collection as time permits. The result, including enantiomers and diastereomers, will be well over 200 additional molecules. A notice will appear in the JCE Featured Molecules column when this new set of molecules is available in JCE Online.

Werner and Jørgensen Bond Theory David M. Whisnant, Laura Yindra
This simulation begins in the period around 1870 when chemistry is beginning to be organized. The concept, introduced by Kekulé and Couper, of tetravalent carbon atoms capable of linking to each other has permitted the rise of structural concepts in organic chemistry.

The Evolution of Bond Theory David M. Whisnant, Laura Yindra
In chemistry lectures we have little time to discuss the history of chemistry. This simulation begins with the development of valence concepts in the 19th century. We will step back into the 19th century to see how theories of chemical combination changed during that time.

Elementary Bingo Robert M. Hanson, Ira M. Hanson
Elementary Bingo is a simple Web page that creates Bingo cards for a classroom or social event activity associated with review and/or learning of the names and symbols of the elements. The essential element of the site is that every time the page is reloaded or printed, a unique set of Bingo cards is produced. As in ordinary Bingo, players receive Bingo cards that have chemical symbols. An announcer picks elements out of a hat (or beaker) and announces a chemical name. Players place markers on the symbol for that element if they have it on their card. Once a player has five across, five down, or five diagonally, they announce, "Bingo!" Their card is checked to see if, indeed, they do have the announced elements present.

Mage; A Tool for Developing Interactive Instructional Graphics Stephen F. Pavkovic
Mage is a graphics program especially well suited for visualizing three-dimensional structures of proteins and other macromolecules. It is an important tool for biochemists and finds many applications in biochemistry courses. We utilize Mage to create interactive instructional graphics of potential use in a wider range of undergraduate chemistry courses, and present some of those applications here.
