A-DNA and B-DNA: Comparing Their Historical X-ray Fiber Diffraction Images Amand A. Lucas
This paper provides a comparative explanation of the structural content of the diffraction diagrams of A-DNA and B-DNA that facilitated the discovery of the double-helical structure of DNA by Watson and Crick in 1953. This analysis is supported a method that simulates both A-DNA and B-DNA X-ray images optically.

Computational Analysis of Stereospecificity in the Cope Rearrangement Laura Glish and Timothy W. Hanks
Experimental product distributions from the Cope rearrangement of disubstituted 1,5-hexadienes can be readily understood by computer modeling of the various possible transitions states. Visual analysis of these geometries allow students to interpret the computational results by analogy to the familiar chair and boat conformations of substituted cyclohexanes.

Determination of the Rotational Barrier for Kinetically Stable Conformational Isomers via NMR and 2D TLC Gregory T. Rushton, William G. Burns, Judi M. Lavin, Yong S. Chong, Perry Pellechia, and Ken D. Shimizu
After the synthesis of a N,N'-diaryl naphthalene diimide, students estimate the rotational barrier about a CarylNimidesingle bond by studying the reequilibration of the two resulting isomers using two-dimensional thin-layer chromatography, followed by a more accurate determination through a 1H NMR time study.

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 GCMS, 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.

The Step-by-Step Robinson Annulation of Chalcone and Ethyl Acetoacetate. An Advanced Undergraduate Project in Organic Synthesis and Structural Analysis Lionel Delaude, Jean Grandjean, and Alfred F. Noels
The Robinson annulation is a three-step process involving a Michael addition followed by an internal aldol condensation and a dehydration. It is possible to stop the reaction after every step and to isolate the three products, allowing students to confirm the validity of the stepwise mechanism and develop a more thorough understanding of the whole process.

Semiempirical and DFT Investigations of the Dissociation of Alkyl Halides Jack R. Waas
Enthalpy changes corresponding to the gas phase heats of dissociation of 12 organic halides were calculated using two semiempirical methods, the HartreeFock method, and two DFT methods. All five methods agreed generally with the expected empirically known trends in the dissociation of alkyl halides.

Synthesis of Unsymmetrical Alkynes via the Alkylation of Sodium Acetylides. An Introduction to Synthetic Design for Organic Chemistry Students Jennifer N. Shepherd and Jason R. Stenzel
Teams of students design a microscale synthesis of an unsymmetrical alkyne using commercially available terminal alkynes and alkyl halides and characterize the resulting products using TLC, IR, and 1H NMR spectroscopy. Depending on the chosen reactants, students observe both substitution and elimination products, or in some cases, no reaction at all.
