Author: R SandersonEditor: ElsevierISBN: Size: 16,18 MBFormat: PDFRead: 885Chemical Bonds and Bonds Energy, Second Edition provides information pertinent to the fundamental aspects of contributing bond energy and bond dissociation energy. This book explores the values that are useful in the interpretation of significant phenomena such as product distribution and reaction mechanisms. Organized into 12 chapters, this edition begins with an overview of the quantitative relationship among three basic properties of an atom, namely, nonpolar covalent radius, electronegativity, and homonuclear single covalent bond energy. This text then examines the quantitative means of evaluating the partial atomic charges that result from initial differences in the electromagnetivity of atoms that form a compound. Other chapters consider the recognition of the reduction of bond weakening not by multiplicity and in certain types of single covalent bonds. The final chapter deals with the application of the principal ideas and techniques to the oxidation of ethane.

Chemical Bonds A Dialog Jeremy K.
Burdett The University of Chicago, USA Understanding the nature of the chemical bond is the key to understanding all chemistry, be it inorganic, physical, organic or biochemistry. In the form of a question and answer tutorial the fundamental concepts of chemical bonding are explored. These range from the nature of the chemical bond, via the regular hexagonal structure of benzene and the meaning of the term 'metallic bond', to d-orbital involvement in hypervalent compounds and the structure of N2O. Chemical Bonds: A Dialog provides. a novel format in terms of a dialog between two scientists. insights into many key questions concerning chemical bonds. an orbital approach to quantum chemistry.
MingosEditor: SpringerISBN: 331933543XSize: 12,29 MBFormat: PDFRead: 139The series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience.
Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed. A description of the physical basis of the experimental techniques that have been used to provide the primary data may also be appropriate, if it has not been covered in detail elsewhere. The coverage need not be exhaustive in data, but should rather be conceptual, concentrating on the new principles being developed that will allow the reader, who is not a specialist in the area covered, to understand the data presented. Discussion of possible future research directions in the area is welcomed. Review articles for the individual volumes are invited by the volume editors.

The theory, modelled after a description of valence electrons in isolated atoms, explains how intrinsic bond energies depend on the amount of electronic charge carried by the bond-forming atoms. It also explains how bond dissociation depends on these charges. While this theory vividly explains thermochemical stability, future research could benefit from a better understanding of bond dissociation: if we learn how the environment of a molecule affects its charges, we also learn how it modifies bond dissociation in that molecule.
