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. The objective is to perform the experiment, determine if any sabotage has occurred, and, if so, identify the changes that were made to the reagents as well as the person responsible.

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.

Simulating How a Virus Spreads through a Population: An Introduction to Acid-Base Chemistry in the Organic Chemistry Laboratory  Ronald M. Jarret
The traditional lab exercise that achieves separation of a mixture of 4-aminoacetophenone and benzoic acid by chemically active extraction has been expanded to include an exercise that uses materials from the extraction experiment to simulate how a virus spreads through a population.

Organic Acids without a Carboxylic Acid Functional Group  G. V. Perez and Alice L. Perez
This paper presents several organic molecules that have been labeled as acids but do not contain a carboxylic acid functional group. Various chemical principles such as pKa, tautomerization, aromaticity, conformation, resonance, and induction are explored.

An Organoleptic Laboratory Experiment  John M. Risley
Compounds in ten different classes of organic molecules that are used in the fragrance and food industry are provided to students. Students whiff the vapors of each compound and describe the organoleptic properties using a set of terms utilized in the fragrance and food industry. A set of questions guides students to an understanding of the relationship between structure of molecules and smell.

An internal comparison of the intermolecular forces of common organic functional groups: A thin-layer chromatography experiment  Beauvais, Robert; Holman, R. W.
Due to the latest trends in organic chemistry textbook content sequences, it has become desirable to develop an experiment that is rapid, simple, and general, that would compare and contrast the various functional group classes of organic molecules in terms of their relative polarities, dipole moments, and intermolecular forces of attraction.

The decarboxylation of organic acid  March, Jerry
Simple aliphatic acids (except for acetic) do not give good yields of the corresponding alkanes through decarboxylation, although many organic chemistry textbooks cite this as a general method for the preparation of alkanes.
