Nanoparticle synthesis is an important area of nanotechnology and has been performed by undergraduate students from various universities across the globe. Due to the availability of massive data on the synthesis of a wide variety of metallic nanoparticles, including silver, gold, selenium, zinc, copper, iron, palladium, platinum, titanium, etc.,…

Preceding even the Hartree-Fock method, molecular integrals are the very foundation upon which quantum chemical molecular modeling depends. Discussions of molecular integrals are normally found only in advanced and technical texts or articles. The objective of the present article is to provide less experienced readers, or students in a…

Chemical laboratory safety education is often synonymous with boring, dry, drawn-out lectures. In an effort to challenge this norm and stimulate vivid learning opportunities about laboratory safety, college chemistry classes analyzed a short, humorous video clip of a character, named Mr. Bean, who visits a chemistry laboratory and commits several…

Introduced is a method for estimating carbon-13 nuclear magnetic resonance (NMR) shifts. The method is brief and simple so that students can use it with ease. (RH)

This chemistry textbook presents a beginning course for schools or colleges. It presents a more complete classification than usual according to chemical analogies, the explanation of chemical phenomena in ordinary language, as well as symbols, and the addition of a complete set of formulae in the appendix. A number of recent and important…

This chemistry textbook presents a beginning course for schools or colleges. It presents a more complete classification than usual according to chemical analogies, the explanation of chemical phenomena in ordinary language, as well as symbolic language. A series of new and original designs are introduced, illustrating to the eye the groupings of…

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

Designed for the organic chemist involved in interpreting NMR spectra, basic concepts of chemical shift equivalence and magnetic equivalence in NMR spectrometry are discussed. (CS)

Presents a figure that aids in unifying stereochemical concepts in organic chemistry instruction. (CS)

This training manual, intended for chemists and technicians with little or no experience in chemical procedures required to monitor drinking water, covers analytical methods for inorganic and organic chemical contaminants listed in the interim primary drinking water regulations. Topics include methods for heavy metals, nitrate, and organic…

Describes an experiment which illustrates the general aspects of intermolecular energy transfer between triplet states in rigid solutions of organic compounds solved in an ethanol-ether mixture. Measurements of quenching and energy transfer processes are made using the chemicals of benzophenone and naphthalene. (CS)

The synthesis of 1,4-diphenylbutadiene by means of the Wittig reaction is presented as suitable for organic chemistry students at the end of a basic laboratory program to apply laboratory skills and display understanding of the use of phase transfer catalysis and its application in syntheses. (CS)

Reports a method of preparation for tris(ethylenediamine)cobalt(III) and tris(2,2'-bipyridine)cobalt(III) that will shorten the preparation time by approximately 3 hours. Notes the time for synthesis and isolation of compound one was 1 hour (yield 38 percent) while compound two took 50 minutes (yield 71%). (MVL)

This textbook aims to divest the subject of chemistry of technicalities, and to present each natural division in a strictly practical form, illustrated by diagrams and experiments so simplified as to be within the comprehension of the youth as well as the adult. The author has observed that many of our academies and schools where chemistry is…

This unit on hydrocarbons is one of 10 first year units produced by the Independent Learning Project for Advanced Chemistry (ILPAC). The unit is divided into sections dealing with alkanes, alkenes, alkynes, arenes, and several aspects of the petroleum industry. Two experiments, exercises (with answers), and pre- and post-tests are included.…
