The Comparative Nucleophilicity of Naphthoxide Derivatives in Reactions with a Fast-Red TR Dye Cheryl M. Mascarenhas
In this experiment, organic chemistry students perform reactions between three naphthyl acetate derivatives and the diazonium salt Fast-Red TR. Students discover under what conditions the hydrolysis and electrophilic aromatic substitution is fastest and slowest, allowing them to conclude that latter, rather than the former, is rate-limiting.

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.

4-Dimethylaminopyridine or Acid-Catalyzed Syntheses of Esters: A Comparison Annemieke W. C. van den Berg and Ulf Hanefeld
Students compare acid-catalyzed ester synthesis and the 4-dimethylaminopyridine-catalyzed reaction. Based on the outcome of the experiments, students discuss the different reaction mechanisms and reason why different products are formed.

Teaching Introductory Organic Chemistry: 'Blooming' beyond a Simple Taxonomy Michael D. Pungente and Rodney A. Badger
Applying Bloom's taxonomy to introductory organic chemistry classes in order to help students construct their own understanding of the material rather than simply memorize it; includes examples of questions at the various cognitive levels.

An Unexpected Event When Chymotrypsin Performs Its Physiological Role Ivan G. Darvey
One of the events that occur during the chymotrypsin-catalyzed hydrolysis of proteins is an example of an exception to a rule of thumb taught in introductory organic chemistry courses, namely, that amides can't readily be converted to esters. If biochemistry teachers and the authors of textbooks of biochemistry commented on this unusual reaction, it would emphasize further the remarkable part chymotrypsin plays as a catalyst in carrying out its main perceived "physiological role".

The Chemistry of Paper Preservation: Part 4. Alkaline Paper Henry A. Carter
The use of alkaline paper can minimize the problem of acidity for new papers. This study focuses on the chemistry involved in the sizing of both acid and alkaline papers and the types of fillers used. The advantages and potential problems in alkaline paper making are also discussed.

Preparation and crosslinking of an unsaturated polyester: An organic chemistry experiment Stevens, M. P.
Unsaturated polyesters are ideally suited for introducing students to polymer chemistry in the laboratory because they are easy to prepare, the use both condensation and addition polymerization, and they serve to demonstrate the techniques involved in preparing the most widely used polymers.
