Stereospecific Synthesis of the Geometrical Isomers of a Natural Product  T. 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.

A Puzzling Alcohol Dehydration Reaction Solved by GC–MS Analysis  Michael W. Pelter and Rebecca M. Macudzinski
The reaction of 2-methyl-2-propanol with ~50% sulfuric acid at 100 ¬ĚC yields isobutylene, which reacts further by a "puzzling" reaction. By coupling the GC/MS analysis of the product mixture with their knowledge of the mechanism of alcohol dehydration and alkene reactivity, students are able to identify the major products of this reaction.
