Electronic Structure Principles and Aromaticity P. K. Chattaraj, U. Sarkar, and D. R. Roy
Electronic structure principles dictate that aromatic molecules are associated with low energy, polarizability, and electrophilicity but high hardness values, while antiaromatic molecules possess the opposite characteristics. These relationships are demonstrated through B3LYP/6-311G** calculations on benzene and cyclobutadiene.

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 himthe 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.

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.

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.

A Substitute for “Bromine in Carbon Tetrachloride” Joshua M. Daley and Robert G. Landolt
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.

The use of words having different colored sides is a excellent way to introduce stereochemical concepts that might not be easily grasped when using molecular examples. We have found that concepts such as enantiomers, diastereomers, identical molecules, chirality, achirality, mirror planes of symmetry, and internal planes of symmetry are readily understood by students when using stereowordimer examples.
