Describes a chemical experiment which illustrates the Beckman rearrangement and ring opening reactions. (SL)

Describes some reactions for the identification and application of cyanuric acid. Suggests students may find this applied chemistry interesting because of the use of cyanuric acid in swimming pools and diesel engines. Lists three tests for cyanate ion and two tests for cyanuric acid. (MVL)

Provides methodology for carrying out the synthesis of sec-butyltoluene by the Friedel-Crafts alkylation of toluene. Suggests using simple elemental aluminum as the catalyst in place of AlCl3 or amalgamated aluminum. Notes satisfactory results for both macro- and microscale operations. (MVL)

Presents an organic chemistry experiment consisting of a two step reaction sequence involving the Grignard synthesis of an alcohol followed by its oxidation to ketone. (SL)

Proposes that the psychological problem of students expecting a particular result in an organic chemistry laboratory and, therefore, working in an unthinking manner be attacked by assigning experiments that give students unexpected results. Gives four examples of such experiments with strategies for teaching them. (CW)

Discusses the kinetic behavior associated with the interaction of metal ions with apocarbonic anhydrase, focusing on the formation of two metallocarbonic anhydrase--the biochemically active Co(II) and the inactive Ni(II)derivatives. (GA)

Discusses the biocidal/toxicological applications of organo derivatives of true metals. (SL)

A laboratory experiment is described which illustrates such concepts as resonance, inductive, steric, and solvation effects in a beginning organic chemistry course. This experiment is designed to encourage students to predict results and interpret their findings. (MR)

Describes an experiment in which students determine the level of cholesterol in serum. (SL)

Describes an organic chemistry experiment for teaching the basic concepts of chemical kinetics. Provides background information about first- and second-order reactions, experimental procedures of the Diels-Alder reaction between cyclopentadiene and dimethyl fumarate, and the experimental results. (YP)

Reports an experimental procedure for a course in physical organic chemistry to illustrate correlation between structure and reactivity. (SL)

Describes a laboratory experiment suitable for undergraduate students which illustrates the oxidative coupling of phenols. (SL)

Presents an improved technique for synthesizing acetanilide from nitrobenzene by reducing nitrobenzene with iron powder and hydrochloric acid. This experiment has been used successfully with 2,000 students during two semesters. (Author/SA)

This undergraduate experiment shows that the inclusion of an appropriate additive can have a very marked effect on the physical properties of a polymer. The polymer used is polypropylene and the additives are 2-hydroxy-4-octyloxy-benzophenone and benzophenone. (BB)

Explains a laboratory exercise where 2-methylpyrazinepentacyanoiron (II) is synthesized by thermal and photochemical pathways. (GA)
