Study of Molecular-Shape Selectivity of Zeolites by Gas Chromatography  Pei-Yu Chao, Yao-Yuan Chuang, Grace Hsiuying Ho, Shiow-Huey Chuang, Tseng-Chang Tsai, Chi-Young Lee, Shang-Tien Tsai, and Jun-Fu Huang
This analytical or physical chemistry sorption experiment uses hexane isomers as probe molecules to demonstrate the "molecular-shape selectivity" behavior of zeolites. Students can also modify the sorption protocol to build their own experiments.

Steam Hydrocarbon Cracking and Reforming  Michael Golombok
We examine steam hydrocarbon reforming and steam hydrocarbon cracking as an example of two processes that operate under different chemical reactivity regimes: equilibrium determined and kinetically determined, respectively. The feed streams and reaction conditions are similar, but the products are different. The role of catalysis for the two processes is compared and the effects on the kinetics are discussed.

Using Hydrocarbon Acidities To Demonstrate Principles of Organic Structure and Bonding  Andrew P. Dicks
This article demonstrates the utility of hydrocarbon acidity as a teaching tool within the undergraduate classroom. Acidities of compounds containing only hydrogen and carbon vary by at least 50 orders of magnitude. Differences in acidities are rationalized by invoking principles of hybridization, resonance, induction, and aromaticity.

Fifty-Year Trends in the Chemical Industry: What Do They Mean for Chemical Education?  Chadwick A. Tolman and George W. Parshall
This article describes some of these changes from the perspectives of the authors, whose careers span most of the preceding half-century. We describe five illustrative technological developments in the industry and changes we have seen in the industrial research laboratory, and offer viewpoints on how these changes affect the educational needs of students going into industrial careers.

A Strategy for Incorporating 13C NMR into the Organic Chemistry Lecture and Laboratory Courses  Perry C. Reeves and Chris P. Chaney
The use of spectroscopy in establishing the structures of molecules is an important component of the first course in Organic Chemistry. However, the point in the course at which these techniques are best introduced remains uncertain. We suggest that carbon nuclear magnetic resonance spectroscopy should be introduced at an early stage of the lecture course, specifically while studying the alkanes, and used extensively for structure determination throughout the course.

S. M. Tanatar and His Contribution to the Field of Thermal Rearrangements  Ludmila Birladeanu
Thermal rearrangements constitute an important chapter in organic chemistry. Surprisingly, the name of its discoverer remains unknown. The present article is meant to remedy this situation by describing some of the work of the 19th century Russian chemist S. M. Tanatar (1849 - 1917) who, based on the thermochemical data provided by Berthelot, envisaged the possibility of transforming cyclopropane into propene under the influence of heat alone.

On the Disproportionations of Cyclohexene and Related Compounds  Alex Bunjes, Ingo Eilks, Manfred Pahlke, and Bernd Ralle*
The catalytic hydrogenation of liquid hydrocarbons is easy to realize in a simple laboratory experiment using a palladium catalyst. In the case of hydrogenation cyclohexen or cyclohexadiene in addition to the expected finding of cyclohexane among the hydrogenation products, the formation of benzene can be observed. In absence of hydrogen, the disproportionation of both starting materials to cyclohexane and benzene takes place.
