An Improved Preparation of 2,4-Dinitrophenylhydrazine Reagent  Ben Ruekberg and Eric Rossoni
In the analysis of aldehydes and ketones (both for characterizing the functional group and identifying such compounds by the melting points of their derivatives), 2,4-dinitrophenylhydrazine reagent is often used. Of the several formulations of this reagent, the most popular uses sulfuric acid. The method involves making a paste of 2,4-dinitro-phenylhydrazine in concentrated sulfuric acid, dispersion of the paste in ethanol, addition of water, and the filtration of the reagent. This improvement uses milder conditions, which may obviate the need for the final filtration. Those responsible for preparation of stock reagent solutions for classes should note that this method facilitates scaling up the preparation.

Scaling Up Effects in the Organic Laboratory  Anna Persson and Ulf M. Lindström
A simple, yet safe and effective set of experiments to expose chemistry students to some of the effects that may be encountered when scaling up an organic reaction is described. The exothermic DielsAlder reaction between maleic anhydride and cyclopentadiene was found to be ideal for our purposes and was performed in small, medium, and large scale for comparison. The observed differences of heat evolution between the three scales were significant. Also, to demonstrate how excess heat evolution can be controlled by simple means, two additional experiments in which the reaction was run either with small glass helices or water present were performed.

Solvent-Free Synthesis of Chalcones  Daniel R. Palleros
The solvent-free synthesis of 20 chalcones was carried out by grinding the benzaldehyde (unsubstituted, 4-methyl, 4-methoxy, 3-chloro, or 4-chloro) and the acetophenone (unsubstituted, 4-methyl, 4-bromo, or 4-methoxy) in the presence of solid sodium hydroxide with a mortar and pestle. In general, the chalcones were obtained in high yields and high purity. Minor quantities of ketol and Michael addition product were detected by NMR spectroscopy. These side-products were easily removed by recrystallization.

The Problem with Organic Chemistry Labs  Jerry R. Mohrig
Despite the educational limitations of cookbook verification experiments, the majority of undergraduate organic chemistry laboratories are still based on them. What is so often missing in these labs is the opportunity for students to interpret their experimental results in the context of a real problem. We need to recast our projects and experiments so that questions serve as the basis for lab investigations. This question-driven, guided-inquiry approach to laboratory teaching will allow students to participate effectively in the process of experimental organic chemistry.
