Mosher Amides: Determining the Absolute Stereochemistry of Optically-Active Amines Damian A. Allen, Anthony E. Tomaso, Jr., Owen P. Priest, David F. Hindson, and Jamie L. Hurlburt
In this experiment, teams of students are given an optically-pure amine of known structure but unknown stereochemistry. Different teams derivatize samples of the amine with (R) and (S) conformations of Mosher's acid chloride. The resulting diastereomers are analyzed by NMR to determine the absolute configuration of the initial, unknown amine.

A Guided-Inquiry Approach to the Sodium Borohydride Reduction and Grignard Reaction of Carbonyl Compounds Robert E. Rosenberg
Students teams identify unknowns and their reaction products and use their data to deduce that esters are less electrophilic than the other carbonyl compounds present, that Grignard reagents are more nucleophilic than sodium borohydride, and that carboxylic acid derivatives do not undergo the nucleophilic addition reactions that are characteristic of aldehydes and ketones.

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.

Making Usable, Quality Opaque or Transparent Soap Suzanne T. Mabrouk
First-year and organic chemistry students will learn the chemistry of soap by making some of the eleven described formulations, which produce usable, quality bars of soap. Opaque and transparent soaps are made in two and three hours, respectively. With an introduction to formulation chemistry, organic chemistry students can devise a formulation to synthesize their own opaque soap. Many of the formulations use commonly-available fats and oils, while some formulations incorporate specialty fats and oils for therapeutic purposes, for example, to relieve dry skin or itching.

Formation of α-Tetralone by Intramolecular Friedel–Crafts Acylation Michael S. Holden, R. David Crouch, and Kathryn A. Barker
A microscale procedure is described for the formation of the industrially-important compound alpha-tetralone. This is an example of an intramolecular FriedelCrafts acylation, utilizing 4-phenylbutanoic acid and a proton source. The title reaction demonstrates the concept of ring-forming reactions and highlights the use of carboxylic acids as an electrophile precursor in electrophilic aromatic substitution reactions.

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.

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.
