Oxidation of Aromatic Aldehydes Using Oxone Rajani Gandhari, Padma P. Maddukuri, and Thottumkara K. Vinod Describes an eco-friendly procedure for the oxidation of aldehydes to carboxylic acids in water or a water-ethanol mixture using Oxone as the oxidant. The use of eco-friendly solvents, a non-toxic reagent, and the elimination of extraction solvents in the procedure demonstrate important green chemistry themes to students.

Developing Critical Thinking Skills: The "Sabotaged" Synthesis of Methyl p-Bromobenzoate Eric J. Mahan and Mary Alice Nading Before beginning an experiment, students are told that someone might have sabotaged their experiment to produce other-than-expected results.

Ozonolysis Problems That Promote Student Reasoning Ray A. Gross Jr. The structural features inherent in acyclic monoterpenes that follow the isoprene rule often lead to unique sets of ozonolysis products from which their structures, excluding stereochemistry, can be determined from molecular formulas only. This article shows how students may elucidate the structures of these compounds by analysis of the oxidative and reductive workup products. Gross, Ray A., Jr. J. Chem. Educ. 2006, 83, 604.

Application of ChemDraw NMR Tool: Correlation of Program-Generated 13C Chemical Shifts and pKa Values of para-Substituted Benzoic Acids Hongyi Wang An application of ChemDraw NMR Tool was demonstrated by correlation of program-generated 13C NMR chemical shifts and pKa values of para-substituted benzoic acids. Experimental 13C NMR chemical shifts were analyzed in the same way for comparison. The project can be used as an assignment at the end of the first-year organic chemistry course to review topics or explore new techniques: Hammett equation, acidbase equilibrium theory, electronic nature of functional groups, inductive and resonance effects, structurereactivity relationship, NMR spectroscopy, literature search, database search, and ChemDraw software.

Analytical Spectroscopy Using Modular Systems Brian M. Patterson, Neil D. Danielson, Gary A. Lorigan, and André J. Sommer This article describes the development of three analytical spectroscopy experiments that compare the determination of salicylic acid (SA) content in aspirin tablets. The experiments are based on UVvis, fluorescence, and Raman spectroscopies and utilize modular spectroscopic components. Students assemble their own instruments, optimize them with respect to signal-to-noise, generate calibration curves, determine the SA content in retail aspirin tablets, and assign features in the respective spectra to functional groups within the active material.

Elucidation of Molecular Structure Using NMR Long-Range Coupling: Determination of the Single Isomer Formed in a Regiospecific Reaction Samuel Delagrange and Françoise Nepveu The experiment presented in this article introduces students to the main concepts of two essential NMR techniques for investigating molecular structure. Heteronuclear multiple bond connectivity (HMBC) and proton-coupled 13C NMR are used to determine which isomer, from a possible two, is formed by a regiospecific reaction. The demonstration, based on long-range coupling between quaternary carbons and protons on neighboring carbons, is presented step by step. Delagrange, Samuel; Nepveu, Françoise. J. Chem.

Preparation and Identification of Benzoic Acids and Benzamides: An Organic "Unknown" Lab Douglass F. Taber, Jade D. Nelson, and John P. Northrop The reaction of an unknown substituted benzene derivative with oxalyl chloride and aluminum chloride gives the acid chloride. Hydrolysis of the acid chloride gives the acid, and reaction of the acid with concentrated aqueous ammonia gives the benzamide. The equivalent weight of the acid can be determined by titration; given this information and the melting points of the acid and the benzamide, it is possible to deduce the structure of the initial unknown.

Reduction of Carboxylic Acids with Sodium Borohydride and an Electrophile Jan William Simek, Thad Tuck, and Kelly Courter Bush Integration of new reduction conditions into a procedure applicable to the first-year organic chemistry laboratory, where reduction of the carboxylic acid group has remained an obstacle, notwithstanding the use of borane or LiAlH4 (2) on the microscale. The NaBH4 method with either electrophile can be modified to any scale; in our hands, the use of I2 as the electrophile performed better at the semimicro scale than the H2SO4 method.
