Describes recent attempts to program computers to map synthetic routes to organic compounds. The computer is provided with structural information for many molecules and reaction descriptions; when a target compound is specified, the computer lists possible precursors, thus indicating possible synthetic routes. (MLH)

Presented is an introduction to the interpretation of electron spin resonance spectra of organic radicals. The article is written for undergraduate college students. (RH)

Explores the extent to which, in polycyclic hydrocarbons, the total pi electron population tends to form small (4n plus 2) groups and avoid the formation of 4n groups. Also discusses the relation of this trend to resonance energy stabilizations. (JN)

Presents a short set of carbon-13 nuclear magnetic resonance (NMR) tables. These tables not only serve pedagogic purposes but also allow students to do calculations rapidly and with acceptable accuracy for a wide variety of compounds. (JN)

Describes steps (using monochiral and multichiral molecules) to enable students to arrive with relative ease at correct stereochemical relationships. The approach assumes familiarity with Fischer projection formulas and assignment of R and S absolute configurations. (JN)

There are two conflicting views about the mechanism of 1,3-dipolar cycloadditions to multibonds. To reconcile these viewpoints a concerted, spin-paired, diradical mechanism, based on valence bond theory, is proposed. Each of these three mechanisms is discussed. (JN)

Discusses factors which control rate and orientation of free radical addition to alkenes. Although based primarily on results involving behavior of alkyl radicals, arguments developed apply to addition of atoms and hetero-radicals to olefins. (JN)

Reviews are presented which are designed for beginning undergraduates. The films are divided into two series: (1) Manipulation of Liquids and Solids, and (2) Chromatographic Separations and Spectorscopic Methods. Topics increase in complexity from one film to the next. (DF)

Discusses a non-traditional unstructured laboratory approach designed to acquaint students with analytical techniques through the identification of two unknowns, one as a single component and one in a mixture, and the reading for the course facilitated by a detailed report on nine syntheses recently reported in the literature. (CP)

In each of three studies, students using computer assisted instruction for supplemental drill and practice in a first organic chemistry course performed consistently higher than control students on sections of the course examinations related to the content of the programs. (AL)
