A systematic approach to naming polyfunctional organic compounds is presented. Latest IUPAC rules are incorporated and the table of order of precedence for the major functional groups is assembled. The scope of nomenclature is limited to common functional groups that are covered by undergraduate courses in colleges and universities. (Contains 1…

The microwave-mediated preparation of lophine (2,4,5-triphenylimidazole) is described. This experiment allows for an introduction to the emerging technology of microwave-assisted organic synthesis while providing an opportunity for students to employ the principles of carbonyl chemistry in devising a mechanism to explain the formation of the…

This new WebWare combines instructional text and Jmol interactive, animated illustrations that help students visualize the mechanism. It is concluded that by animating the fluxional behavior of a simple model for chiral metal catalyst Sn(amidinate)[subscript 2], in which axial/equatorial exchange within the amidinate rings occurs through a Berry…

Tips that laboratory researchers and beginning graduate students can use to safeguard against explosion hazard with emphasis on clear illustrations of molecular structure are discussed. Those working with hazardous materials must proceed cautiously and may want to consider alternative and synthetic routes.

Describes the use of disc or ring magnets magetized axially and iron discs, in conjunction with an overhead projector, as a model of nuclear structure and of complete molecules. (GS)

Describes how to use the distinctive properties of osazone formation in conjunction with molecular model construction to demonstrate the relationship between the three-dimensional structures of simple sugars and the shapes of crystals they form. (BR)

Describes an experiment, for the general chemistry laboratory, intended to introduce the student to infrared spectroscopy. After being introduced to the theory of molecular vibrations on an elementary level, each student receives a list of 5-7 nickel (II) ammines to be prepared, analyzed and characterized by infrared spectoscopy. (MLH)

Describes an experiment designed for second-level summer school chemistry students enrolled in Great Britain's Open University. (GS)

Describes a dry-lab experiment in which the student is provided with a set of fluorescence spectra of quinine for study and interpretation. (MLH)

Discusses two different uses of information theory in chemistry to present entropy and chemical structure analysis. (GA)

A number of phase transfer catalysis reactions are illustrated. (CP)

Proposes use of the Hammett relationship in the framework of a frontier orbital method for explanation of chemical reactivity. (CP)

Introduces a simple one-dimensional model of a diatomic molecule that can explain all the essential features of a real two particle quantum mechanical system and gives quantitative results in fair agreement with those of a hydrogen molecule. (GA)
