Communicating about Matter with Symbols: Evolving from Alchemy to Chemistry  Luigi Fabbrizzi
Alchemists used a secret language and arcane symbols to indicate substances and procedures. When alchemy became quantitative and evolved into the discipline of chemistry, those symbols were supplanted by abbreviations and formulas. However, chemical communication can remain mysterious to the uninitiated.

A Short History of Three Chemical Shifts  Shin-ichi Nagaoka

Nevertheless, the "chemical" environment around an atom of interest influences the electronic environment and hence, leads to spectral shifts, making the prefix "chemical" appropriate.

Was Markovnikov's Rule an Inspired Guess?  Peter Hughes
A study of 19th century literature shows that neither Markovnikov nor any of his contemporaries carried out the reactions often attributed to himthe addition of hydrogen bromide or hydrogen chloride to propene. Since there is little evidence for Markovnikov's rule in his 1870 article, it is likely that it was more of an inspired guess than a rational conclusion.

A catalyst is placed inside a gas chromatograph injector liner and the reactants injected, vaporized, and led through the catalyst bed by the carrier gas for reaction. By controlling the GC injector temperature, varying the carrier gas, its flow rate, and injecting different quantities of the reactant, several parameters in heterogeneous catalysis can be determined.

Cis and Trans Isomers of Cycloalkenes  Susan E. Barrows and Thomas H. Eberlein
The purpose of this article is to provide that analysis. In order for a cycloalkene to accommodate a trans double bond one or more of the following nonideal geometries must occur: a twisted p bond; pyramidal sp2-carbon atoms; nonideal sp3 bond angles; or longer than normal CC single and double bonds. This article provides a list of experimentally determined relative energies of the cis and trans isomers within the series cycloheptenecycloundecene, along with computationally derived energies at several levels of theory. It also examines the geometric distortions through which cycloalkenes relieve the strain introduced by a trans double bond.

The Addition of Bromine to 1,2-Diphenylethene   Judith C. Amburgey-Peters and LeRoy W. Haynes
We investigated the reaction of (Z)-1,2-diphenylethene (cis-stilbene) with various brominating reagents and solvents following directions in standard organic chemistry manuals. We were particularly interested in learning which combination of brominating reagent and solvent gave the best yield of (d,l)-1,2-dibromo-1,2-diphenylethane without the formation of significant amounts of meso-1,2-dibromo-1,2-diphenylethane, which is essentially the sole product from the reaction of bromine with (E)-1,2-diphenylethene (trans-stilbene). Based on the results from the standard preparatory methods, some permutations of solvent and brominating reagent were tried.

The main purpose is to allow students to practice transferrable skills by handling concrete kitchen materials; they learn classification, ordering, unit conversion, and conservation. The kitchen activities also introduce anchors for chemistry-specific skills such as periodic table conformation and manipulation, chemical equation and chemical formula use, relative mass, and element and compound differentiation.

Benzotrifluoride (BTF) is a suitable solvent substitute for carbon tetrachloride in experiments requiring application of bromine (Br2) in free radical or addition reactions with organic substrates. A 1 M solution of Br2 in BTF may be used to distinguish hydrocarbons based on the ease of abstraction of hydrogen atoms in thermally or light-induced free radical substitutions. Efficacy of minimization of solvent use, by aliquot addition to neat samples, has been established.

A six-period laboratory exercise has been developed that uses the convenient Sharpless asymmetric dihydroxylation (AD) to illustrate the principles of a chiral synthesis. Using one particular alkene, students perform a racemic dihydroxylation, an AD using a commercially available AD-mix, and then an AD using an ester derivative of dihydroquinidine that they synthesized themselves. The structures of the products are confirmed with 1H NMR spectroscopy and the enantiomeric excesses of the diols are determined using a chiral GC column.

Organic Nomenclature  David B. Shaw and Laura R. Yindra
Organic Nomenclature is a drill-and-practice exercise in naming organic compounds (using both common and IUPAC names) and identifying structural formulas. It consists of multiple-choice questions where a name or formula is given and the correct formula or name is chosen from a list of five possible answers.

This test showed that most of the students had an inadequate grasp of the meaning of all five symbols. It also showed that, on the average, their understanding of symbols was more problematic than their understanding of words.

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.

A History of the Double-Bond Rule  Bernard E. Hoogenboom
From his experience as an industrial chemist, Otto Schmidt recognized the bond weakening in hydrocarbons and in 1932 postulated the "Double-Bond Rule," stating that the presence of a double bond in a hydrocarbon has an alternating strengthening and weakening effect on single bonds throughout the molecule, diminishing with distance from the double bond.

Incorporating Organic Name Reactions and Minimizing Qualitative Analysis in an Unknown Identification Experiment  Claire Castro and William Karney
The authors have developed a new type of unknown identification experiment for the introductory organic chemistry laboratory. The unknown sample the student is provided with is the product of an organic name reaction. The student is only informed of the starting material and conditions used in the compound's synthesis, and must then: (1) deduce the compound's structure, (2) determine the name reaction and corresponding mechanism that yields the compound, and (3) present his/her results to the class.

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.

Aromaticity Today: Energetic and Structural Criteria  Mikhail Glukhovtsev
The present paper addresses current controversies in development and applications of the two main criteria of aromaticity, namely, energetic and structural criteria. Various types of resonance energy with an emphasis on homodesmotic and isodesmic stabilization energies are discussed. Reliability of such structural criteria of aromaticity as equalization of carbon-carbon bond lengths and stability with respect to out-of-plane distortions of a molecular structure are analyzed using various examples.

An Alternative Derivation of the Energy Levels of the "Particle on a Ring" System  Alan Vincent
If the linear box is bent round into a ring, acceptable wave functions are those which are continuous at the 'join'. On this model some acceptable linear functions become unacceptable for the ring and some unacceptable cosine functions become acceptable. This approach can be used to produce a straightforward derivation of the energy levels and wave functions of the particle on a ring.
