Background information and experimental procedures are provided for a Prins reaction (condensation of an aldehyde with an alkene). The preparation of 4-(4-hydroxy, 3-methoxy-phenyl) 5-methyl, 1,3-dioxane realized from isoeugenol (natural plant product, commercially available) can be completed in a three-hour laboratory period.

A simple, three-step procedure for synthesizing a dipeptide from its component amino acids is described. The dipeptide synthesized uses inexpensive amino acids having hydrocarbon side-chains and can be observed in E/Z forms by nuclear magnetic resonance spectroscopy. Each step in the synthesis produces white crystalline products using standard…

Describes a simple, three-step synthesis of two cage molecules, birdcage hydrocarbon (VIII) and its homologue, the homobirdcage hydrocarbon IX. Indicates that all products are easily purified and formed in high yields in this activity suitable for advanced undergraduate laboratory courses. (Author/JN)

Results from two surveys of chemists and educators conducted at two conventions indicate weak spots in facilities, poor storage information, and failure to take precautions against reactive hazards. Includes suggestions and a checklist related to a wide range of storage problems. (SK)

Discusses merits of using sigma-pi model of ethylene as a teaching aid in introductory organic chemistry. The nonmathematical treatment of sigma-pi bonding is then extended to such phenomena as conjugation, hyperconjugation, Markovnikoff addition, aromaticity, and aromatic substitution. (SK)

Discusses the importance of teaching the Bohr atom at both freshman and advanced levels. Focuses on the development of Bohr's ideas, derivation of the energies of the stationary states, and the Bohr atom in the chemistry curriculum. (SK)

Provides rationale and objectives for presenting chemical reactions in a unified, logical six-stage approach rather than a piecemeal approach. Stages discussed include: introduction, stable electronic configurations and stable oxidation states, reactions between two free elements, ion transfer/proton transfer reactions, double displacement…

Focusing on research is suggested as an approach for teaching organic chemistry for nonmajors. Topics of saturated hydrocarbons and unsaturated hydrocarbons are used as examples to illustrate the approach. (SK)

The laboratory of an organic chemistry course for dietetics students is based on the learning cycle approach (exploration, invention-concept introduction, and concept application). The laboratory program is divided into four sections: lab techniques, compound types, reaction types, and reaction characteristics. (SK)

Outlines content and use of slide audiotape pre-lab lectures at California State College (Stanislaus). Includes advantages of using the materials and data, indicating their success as teaching aids. (Author/SK)

Describes a two-quarter, freshman honors laboratory course at the Ohio State University, including selection of students, nature of experiments, and safety precautions. Specific instructions are not given to students, who then run reactions under conditions they devise. (SK)

A 10-12 class session unit, based on a series of worksheets (available from the author), is described, including objectives, major topics covered, and instructional and study strategies. A brief pilot evaluation indicates positive student and teacher attitudes toward the unit. (SK)

General course content of and instructional strategies for two high school chemistry courses are described. Includes a list of experiments done during the 40-week school year. (SK)

Briefly describes NSF-funded weekend courses at Western Illinois University. Includes a list of 16 courses with topic and enrollment data and a list of topics in which teachers felt a need for more preparation. (SK)

Students develop and use actual instrumentation in this course which focuses on analog computers, digital electronics, computer interfacing, and online computer techniques. Includes a student handout on the design of a bridge amplifier unit. Mimeographed experiment directions are available from the authors. (SK)
