Addition Reactions of Alkenes The Diels-Alder reaction, addition of oxygen to tetrakis(N, N-dimethylamino) ethylene, polymerization of ethylene, and addition of iodine to a-pinene are demonstrated. Molecular models of ethene are shown.
Quantitative Measurement of Trans-Fats by Infrared SpectroscopyEdward B. Walker, Don R. Davies, and Mike Campbell FTIR-ATR spectroscopy provides an efficient analytical tool to measure the percentage of trans-fat in several commercially available lipids and the degree of alkene isomerization induced by brominationdebromination chemical reactions. Walker, Edward B.; Davies, Don R.; Campbell, Mike. J. Chem. Educ.2007, 84, 1162.

Stereospecific Synthesis of the Geometrical Isomers of a Natural ProductT. Grove, D. DiLella, and E. Volker Presents an experiment for the synthesis of (Z) and (E) isomers that is presented to students as a puzzle in which they must determine the identity of the major component in anise oil. A necessary part of the analysis is the preparation the (E) and (Z) isomers of anethole. Molecular modeling is used to explore the conformation of and energy difference between isomers. Grove, T.; DiLella, D.; Volker, E. J. Chem. Educ.2006, 83, 1055.
