Available in PDF, EPUB and Kindle. Book excerpt: In 1965 a book by P. Bartlett appeared under the title "The Nonclassical Ions" 1). The book is a collection of papers reprinted from various journals. The many reviews that have appeared since 2-22) are either antiquated (the book published in 1972 12) covers the literature mainly before 1968) or relatively biased (e.g., 3.4,10» on brief 2, 7,11). This review attempts to discuss the various points of view on the "nonclassical" carbocations. The main point is to establish the relative role of "nonclassical" and "classical" ions in various chemical processes. The author has followed P. Bartlett's advice 1) that when setting forth the achievements of the human mind one should see how we came to the modern understanding of a given problem (" ... how we know what we know"). The theory of "nonclassical" ions offers an explanation of many unique chemical, stereochemical and kinetic peculiarities of bicyclic compounds. It has expanded our knowledge on chemical bonds in carbocations by introducing electron-deficient bonds (as in boron hydrides). It has accounted for many rearrangements of stable cations. As a "side" result our knowledge has been extended about ionization processes in a solution, as well as about stereochemical methods. 2 Main Terms of Nonclassical Carbocations In 1939 Hevell, Salas and Wilson 23) assumed an intermediate, "bridge" ion 2 to be formed when camphene hydrochloride 1 is rearranged into isobornyl chloride 3. This happened 17 years after Meerwein first postulated the intermediate formation of "carbonium" ions in chemical reactions.

Download or read book Reaction Mechanisms in Sulphuric Acid and other Strong Acid Solutions written by M Liler and published by Elsevier. This book was released on 2012-12-02 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reaction Mechanisms in Sulfuric Acid and other Strong Acid Solutions covers the reactivity in sulfuric acid and other strongly acid solutions. This book is composed of five chapters that emphasize the measure of acidity of sulfuric acid and other acid solutions. Chapters 1 and 2 discuss the physical, thermodynamic, spectroscopic properties, and acidity functions of sulfuric acid/water mixtures. Chapters 3 and 4 examine the protonation and more complex modes of ionization of compounds in these acidic media. Chapter 5 outlines first the possible mechanisms of reactions in acid solutions followed by a discussion of mechanistic criteria that have been developed in order to distinguish between kinetically indistinguishable alternatives. This chapter also presents some methods of kinetic investigation, which are specific to concentrated sulfuric acid solutions. Inorganic chemists and researchers, teachers, and students will find this book invaluable.

Download or read book Electronic Interpretation of Organic Chemistry written by F. M. Menger and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most standard texts in basic organic chemistry require the student to memorize dozens of organic reactions. This is certainly necessary to master the discipline. Unfortunately, most texts do not emphasize why these reactions occur and, just as important, why other reactions that might seem conceivable to the student do not occur. Without this understanding, students tend to forget what they have memorized soon after the course is over. It is the purpose of this book to familiarize the student with the principles governing organic reactivity and to provide a "feel" for organic chemistry that is impossible to secure by memory alone. Digesting the ideas in this book will, we hope, not only explain the common organic reactions but also allow the student to predict the prod ucts and by-products of reactions he has never seen before. Indeed, the creative student might even become capable of designing new reactions as might be required in a complex organic synthesis. In Chapter 1, we cover the basic principles including bonding, nuclear charge, resonance effects, oxidation-reduction, etc. It is a brief discussion, but it nonetheless provides the basis for understanding reaction mechanisms th~t will be treated later on. We highly recommend that this material be reviewed and that the v VI PREFACE problems be worked at the end of the chapter. Answers are given to all problems. In Chapter 2, reaction mechanisms are presented in an increas ing order of difficulty.

Download or read book Electron Impact Phenomena written by F. H. Field and published by Academic Press. This book was released on 2013-10-22 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron Impact Phenomena and the Properties of Gaseous Ions, Revised Edition deals with data pertaining to electron impact and to molecular gaseous ionic phenomena. This book discusses electron impact phenomena in gases at low pressure that involve low-energy electrons, which result in ion formation. The text also describes the use of mass spectrometers in electron impact studies and the degree of accuracy obtained when measuring electron impact energies. This book also reviews relatively low speed electrons and the transitions that result in the ionization of the atomic system. This text then discusses diatomic molecules whose mass spectra can be interpreted using the Franck-Condon principle. This selection also presents some examples of ions in solution that resemble the gaseous ions formed by electron impacts. The energies of these gaseous ions can be the key to understanding the mechanisms of ionic reactions. These examples include the olefin addition reactions and catalytic cracking. This text will prove invaluable for research chemists, students, and professors in chemistry and related fields such as organic chemistry and electrochemistry.
