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.

Capillary Electrophoresis Analysis of Substituted Benzoic Acids. An Experiment for the Organic Synthesis Laboratory  Nancy S. Mills, John D. Spence, and Michelle M. Bushey
We have introduced an experiment into the organic chemistry sequence, in the synthesis laboratory, that utilizes capillary electrophoresis to evaluate the pKa shift on a series of student-prepared substituted benzoic acids. The pKa shift is examined in reference to the electrophoretic-migration behavior of benzoic acid and is a result of the electron-withdrawing or electron-donating characteristics of the substituent. This strategy allows us to increase the exposure of students to modern methods of separation. We are using repeated exposure to increase students' knowledge of separation strategies and techniques.

Hydrogen Bonds Involving Transition Metal Centers Acting As Proton Acceptors  Antonio Martín
A short review of the most remarkable results which have recently reported M----H-X hydrogen bonds, along with a systematization of their structural and spectroscopic properties, is provided in this paper. These M----H interactions are substantially different from the "agostic" M----H ones, and their differences are commented on, setting up criteria that permit their clear differentiation in order to avoid some of the misidentifications that occurred in the past.
