"As Simple as Possible, but Not Simpler"—The Case of Dehydroascorbic Acid  Robert C. Kerber
Textbooks routinely assign dehydroascorbic acid a tricarbonyl structure that is highly improbable in aqueous solution and inconsistent with its colorless appearance. Studies of oxidized forms of ascorbic acid are summarized here, and a plea is entered for accurate descriptions of chemical structures in this and other cases, even at the cost of some simplicity.

A Knoevenagel Initiated Annulation Reaction Using Room Temperature or Microwave Conditions  A. Gilbert Cook
The product of a Knoevenagel initiated annulation reaction is identified through a guided prelab exercise of the synthesis of the Hagemann ester, and then through the analysis of GCMS, NMR, and IR spectra. The stereochemistry of the product is determined through the NMR spectrum and Karplus curve, and the student is required to write a mechanism for the reaction.

Assigning the NMR Spectrum of Glycidol: An Advanced Organic Chemistry Exercise  Eric Helms, Nicholas Arpaia, and Melissa Widener
This exercise combines conformational analysis and 1-D and 2-D NMR spectroscopy to correctly assign the proton and carbon NMR spectra of 2,3-epoxy-1-propanol (glycidol). In the process, students learn how to read DEPT-135, HETCOR, and COSY spectra.

Mechanisms That Interchange Axial and Equatorial Atoms in Fluxional Processes  Marion E. Cass, Henry S. Rzepa, King Kuok Hii
The Berry pseudorotation is a classical mechanism for interchanging axial and equatorial ligands in molecules with trigonal bipyramidal geometry. Teaching this mechanism presents particular pedagogic problems due to both its dynamic and three dimensional character. The approach taken here illustrates these processes using interactive animations embedded in a Web page and overcomes many limitations of a printed page.
