Helping Students Assess the Relative Importance of Different Intermolecular Interactions Paul G. Jasien A semi-quantitative model has been developed to estimate the relative effects of dispersion, dipoledipole interactions, and H-bonding on the normal boiling points for a series of simple, straight-chain organic compounds. Application of this model may be useful in addressing student misconceptions related to the additivity of intermolecular interactions. Jasien, Paul G. J. Chem. Educ. 2008, 85, 1222.

Origin of the Formulas of Dihydrogen and Other Simple Molecules Andrew Williams The logic and experimental data are described with which chemists originally deduced the formulas of fundamental substances such as H2, H2O, Cl2, NH3, CH4, and HCl. It is argued that high school and first-year undergraduate students would gain substantially from exposure to this process. Williams, Andrew. J. Chem. Educ. 2007, 84, 1779.

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. Chattaraj, P. K.; Sarkar, U.; Roy, D. R. J. Chem. Educ. 2007, 84, 354.

Let Us Give Lewis Acid–Base Theory the Priority It Deserves Alan A. Shaffer The Lewis concept is simple yet powerful in its scope, and can be used to help beginning students understand reaction mechanisms more fully. However, traditional approaches to acid-base reactions at the introductory level ignores Lewis acid-base theory completely, focusing instead on proton transfer described by the Br?nsted-Lowry concept.

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. Hughes, Peter. J. Chem. Educ. 2006, 83, 1152.

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. Shepherd, Jennifer N.; Stenzel, Jason R. J. Chem.

Kinetics of Alcohol Dehydrogenase-Catalyzed Oxidation of Ethanol Followed by Visible Spectroscopy Kestutis Bendinskas, Christopher DiJiacomo, Allison Krill, and Ed Vitz A two-week biochemistry experiment was introduced in the second-semester general chemistry laboratory to study the oxidation of ethanol in vitro in the presence of the enzyme alcohol dehydrogenase (ADH). This reaction should pique student interest because the same reaction also occurs in human bodies when alcoholic drinks are consumed. Procedures were developed to follow the biochemical reaction by visible spectroscopy and to avoid specialized equipment. The effect of substrate concentration on the rate of this enzymatic reaction was investigated during the first week. The effects of temperature, pH, the specificity of the enzyme to several substrates, and the enzyme's inhibition by heavy metals were explored during the second week. Bendinskas, Kestutis; DiJiacomo, Christopher; Krill, Allison; Vitz, Ed. J. Chem. Educ. 2005, 82, 1068.

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. Amburgey-Peters, Judith C.; Haynes, LeRoy W. J. Chem.

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. Daley, Joshua M.; Landolt, Robert G. J. Chem. Educ. 2005, 82, 120.
