Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of Nonbenzenoid Aromatic Compounds — II is a collection of plenary lectures presented at the Second International Symposium on the Chemistry of Nonbenzenoid Aromatic Compounds. Starting with a review of the synthesis and study of select heterocycles, the book includes results and developments in this area. A significant part of the reviews of nonbenzenoid aromatic compounds is the examination of annulenese that contain larger Huckel systems than benzene. The demand for better synthetic methods in the study has increased as bridged annulenes have been made for suitable models of testing theoretical concepts. Early studies on some nonbenzenoid aromatic compounds and the related problems are also discussed. A description of the syntheses of several polycyclic systems that contain potential cyclobutadiene rings follows. Studies are made on 8-oxoheptafulvene chemistry after earlier chemical and physical examination of heptafulvene and related compounds provided avenues for research. Some aspects of strained systems, [4]annulene and its Ch+adduct are reviewed in terms of usefulness when applying a theoretical guide, proving the calculations and experiments. Studies on higher membered annulenyl ions belonging to five groups are also discussed. Research chemists, students, and professors in chemistry and related fields such as organic chemistry will find this collection useful.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Theoretically Interesting Molecules: A Research Annual, Volume 2 provides information pertinent to the dynamics of cyclooctatetraene ring inversion. This book deals with bridgehead olefins, which helps to shed light on structure-activity relationships for this most basic functional group. Organized into four chapters, this volume begins with an overview of the involvement of planar, delocalized transition states to account for bond shifting in cyclooctatetraenes, which faces explicit problems in rationalizing the universally low energy demands. This text then examines the carbon-carbon double bond, which is the most ubiquitous functional group in organic chemistry. Other chapters consider the condensed polycyclic benzenoid aromatic hydrocarbons (PAHs), which is a subset of the multifarious class of polynuclear aromatics. This book discusses as well the problem of categorizing the molecular structures of PAHs. The final chapter deals with the reactions and synthesis of Dewar furan. This book is a valuable resource for organic chemists.

Download or read book Nonbenzenoid Aromatics written by James P. Snyder and published by Elsevier. This book was released on 2013-10-22 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonbenzenoid Aromatics, Volume II, provides an overview of the state of knowledge in the field of non-benzenoid aromatic compounds. The theme that threads its way through the six chapters is that of ""aromaticity,"" with each author making an effort to evaluate this concept in light of his own work. It is with this in mind that this treatise was initiated with an historical account tracing the development of the idea up to the discovery of the electron. The book begins with discussions of the estimation of the thermochemical and kinetic stability of a system which has not yet been synthesized and the calculation of electronic spectra. This is followed by separate chapters on the electron spin resonance (ESR) spectra of radical ions of nonbenzenoid aromatics; the theoretical and empirical bases of exaltation; and treatment of cyclic (4n + 2) p-electron systems with six or more p-electrons and bearing one or more formal charges. Subsequent chapters deal with the chemical binding and delocalization in phosphonitrilic derivatives, and cyclobutadiene-metal complexes.

Available in PDF, EPUB and Kindle. Book excerpt: Where are the origins of chemical ideas? How did the pioneers in chemistry recognize the fundamental intellectual issues of their time? What skills of reasoning and experiment did they use to solve these problemes? How did the circumstances of personality and competition influence their careers and scientific accomplishments? If we can answer these questions, we may be able to improve our own chances of success in research. »This is a marvelous book of people and chemical ideas! The author, Jerry Berson, is known as a chemical stylist, a physical organic chemist possessed of the highest analytical powers. In a unique approach to the history of chemistry (indeed the history of science) he brings that style, as well as his insider's knowledge and a perceptive sensivity to the societal setting of chemists, to the analysis of some key chapters in modern organic chemistry.« Roald Hoffmann, Nobel Laureate

Download or read book The Chemist s Companion written by Arnold J. Gordon and published by John Wiley & Sons. This book was released on 1973-01-19 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here in one source is a wide variety of practical, everydayinformation often required by chemists but seldom found together,if at all, in the standard handbooks, data collections, manuals,and other usual sources. Discussing physical, chemical, andmechanical properties of substances and systems, the authors answersuch questions as: * How do I test for and destroy peroxides in different solventsand what is the best way to purify such solvents? * What are the structure, physical properties, and recentreferences to the use of common-name solvents and solvent aids suchas the "Skellysolves," "Cellosolves," "Crownanes," and"Glymes"? * What is the utility of a particular molecular sieve, orpermeation gel, or epoxy cement, or liquid crystal, and where do Ibuy them and find references to their application? The book is divided into nine chapters and covers properties ofatoms and molecules, spectroscopy, photochemistry, chromatography,kinetics and thermodynamics, various experimental techniques, andmathematical and numerical information, including the definitions,values, and usage rules of the newly adopted International Systemof Units (SI Units). A section on statistical treatment of datawhich provides an actual least-squares computer program is alsoincluded. In the spectroscopy chapter, very extensive andup-to-date collections of spectral correlation data are presentedfor ir, uv-vis, optical rotation, nmr, and mass spectra, along withdata on esr and nqr spectroscopy. Also included is a variety ofhard-to-classify but frequently sought information, such as namesand addresses of microanalysis companies and chemistry publishers,descriptions and commercial sources of atomic and molecular models,and safety data for hazardous chemicals. More than 500 keyreferences are also included, most of which are recent. There areimportant hints and definitions associated with the art as well asthe state of the art for the appropriate subjects. Also foundthroughout the book are about 250 suppliers and directions forobtaining special booklets or other material. Containing a wealth of useful information, The Chemist'sCompanion will be an indispensable guide for students andprofessional chemists in nearly all the chemical disciplines. Inaddition, it will provide for the teacher and student an unusualadjunct for use in a broad cross-section of chemistry courses.

Available in PDF, EPUB and Kindle. Book excerpt: Historically, the scientific method has been said to require proposing a theory, making a prediction of something not already known, testing the prediction, and giving up the theory (or substantially changing it) if it fails the test. A theory that leads to several successful predictions is more likely to be accepted than one that only explains what is already known but not understood. This process is widely treated as the conventional method of achieving scientific progress, and was used throughout the twentieth century as the standard route to discovery and experimentation. But does science really work this way? In Making 20th Century Science, Stephen G. Brush discusses this question, as it relates to the development of science throughout the last century. Answering this question requires both a philosophically and historically scientific approach, and Brush blends the two in order to take a close look at how scientific methodology has developed. Several cases from the history of modern physical and biological science are examined, including Mendeleev's Periodic Law, Kekule's structure for benzene, the light-quantum hypothesis, quantum mechanics, chromosome theory, and natural selection. In general it is found that theories are accepted for a combination of successful predictions and better explanations of old facts. Making 20th Century Science is a large-scale historical look at the implementation of the scientific method, and how scientific theories come to be accepted.
