Because the names, interrelations, and oxidation levels of the organic compounds of phosphorus and sulfur tend to confuse students, a simple way to organize these compounds has been developed. The system consists of grouping them by oxidation state and extent of carbon substitution. (JN)

A senior-level, elective course on synthetic fuels was developed for chemistry and chemical engineering majors. The topics covered in this course, instructional strategies used, and independent student projects are described. (JN)

Discusses various issues related to colorblind students performing titrations with visual indicators. Includes tables showing precisions in the titration of a weak acid by colorblind students using phenolphthalein and thymolphthalein and in the titration of a weak base by colorblind persons using methyl red and bromcresol green. (JN)

The standard addition titration is a precise and rapid method for the determination of the acidity in rain or snow samples. The method requires use of a standard buret, a pH meter, and Gran's plot to determine the equivalence point. Experimental procedures used and typical results obtained are presented. (JN)

Reports on the adaptation of a kinetic method of analysis of metal ions for use in an undergraduate teaching laboratory. Background information, procedures used, and analysis of typical results obtained are provided. (JN)

Background information, procedures used, and typical results obtained are provided for an experiment that examines the ability of nuclear magnetic resonance (NMR) to distinguish between structural isomers via resonance multiplicities and chemical shifts. Reasons for incorporating the experiment into organic, analytical, or physical chemistry…

Describes an experiment that involves the extraction of lead from gasoline into an aqueous solvent using iodine monochloride reagent. This method (which avoids the aspiration of organic solvents) also illustrates the use of wavelengths other than the most sensitive wavelength and effects of flame stoichiometry and burner height upon absorbance.…

Describes an undergraduate organic chemistry experiment (requiring three/four 3-hour laboratory sessions) involving a four-stage synthesis of 1-phenyl-1,2,3,4-tetrahydroisoquinolines via the Pictet-Spengler route. In addition, the experiment allows students to study the spectra and properties of aklaloid-like materials while completing several…

Background information, experimental procedures used, and typical results obtained are provided for an experiment that demonstrates the stereospecific arrangement of cyclopropyl halides to allylic halides. (JN)

Describes the use of phase transfer conditions to prepare a sulfur and phosphorus ylide. Background information and procedures are provided for the experiment (which can be completed in one three-hour laboratory period). (JN)

Presents (1) a list of American Chemical Society (ACS) chemistry examinations available for the 1985 testing program (including seven new tests) and (2) condensed norms for the most recent tests (including Brief Organic Chemistry Form 1984-B and High School Advanced Chemistry Form 1984-ADV). (JN)

Presents a sample contract for disposing of hazardous wastes in an environmentally sound, timely manner in accordance with all federal, state, and local requirements. Addresses situations where hazardous waste must be disposed of outside the laboratory and where alternate disposal methods are not feasible. (JN)

Methods used to investigate problems in the sciences include building-up strategies, insight, and change (or serendipitous discovery). Discusses appropriate learning experiences for the undergraduate science students so they are more likely to benefit from the second method of scientific discovery as they make a career in their chosen field. (JN)

Reports on the colors observed during titrations of 15 natural indicators obtained from common fruits and vegetables. These edible indicators can be used for a variety of teacher demonstrations or for simple student experiments. (JN)

Describes a senior-level course that: (1) focuses on the structure and reactions of macromolecules; (2) treats industrial polymers in a unified way; and (3) uses analysis of conformation and conformational statistics as a unifying approach. Also discusses course topics, including polysaccharides, proteins, nucleic acids, and others. (JN)
