Available in PDF, EPUB and Kindle. Book excerpt: It was not until 1971 that the authority for defining scientific units, the General Conference of Weights and Measures got around to defining the unit that is the basis of chemistry (the mole, or the quantity of something). Yet for all this tardiness in putting the chemical sciences on a sound quantitative basis, chemistry is an old and venerable subject and one naturally asks the question, why? Well, the truth is that up until the mid-1920s, many physicists did not believe in the reality of molecules. Indeed, it was not until after the physics community had accepted Ernest Rutherford's 1913 solar-system-like model of the atom, and the quantum mechanical model of the coupling of electron spins in atoms that physicists started to take seriously the necessity of explaining the chemical changes that chemists had been observing, investigating and recording since the days of the alchemists.

This book was released on 2013-03-14 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: For Louis Pasteur, the two distinctive properties of dissymmetric systems, optical activity and chiral discrimination, provided prime evidence for a Divine origin to the universe. Handedness appeared to be built into the macrocosm of the galaxies, each with a non-superposable mirror image by virtue of its rotation, as well as the microcosm of each molecule of most natural products. The best that the chemist in the laboratory could accomplish appeared to be the synthesis of the detordu internally-compensated meso-form and, as Pasteur ultimately came to admit, the externally-compensated racemic form. In the latter case the chemist generated not merely one but two chiral structures, although parity, and secondary symmetry generally, seemed to be conserved in the enantiomer antipode pair. The cosmic element in the Pasteur tradition received an augmentation in secular form from demonstrations of the non conservation of parity in the weak interactions, and from the discovery of net circularity in the extra-terrestrial photons, such as those from the less-distant planets, particularly the photons from the Jupiter red-spot. The development of the photoacoustic circular analysers a decade ago was received in fact with as much enthusiasm by the astronomers as by the chemists. It would be just to add, however, that the majority of these circular analysers are now to be found, not in the observatories, but in the physical and chemistry laboratories devoted to the molecular aspects of the Pasteur tradition.

Available in PDF, EPUB and Kindle. Book excerpt: Offering a comprehensive narrative of the early history of stereochemistry, Dr Ramberg explores the reasons for and the consequences of the fundamental change in the meaning of chemical formulas with the emergence of stereochemistry during the last quarter of the nineteenth century. As yet relatively unexplored by historians, the development of stereochemistry - the study of the three-dimensional properties of molecules - provides a superb case study for exploring the meaning and purpose of chemical formulas, as it entailed a significant change in the meaning of chemical formulas from the purely chemical conception of 'structure' to the physico-chemical conception of molecules provided by the tetrahedral carbon atom. This study is the first to treat the emergence of the unique visual language of organic chemistry between 1830 and 1874 to place in context the near simultaneous proposal of the tetrahedral carbon atom by J.H. van 't Hoff and J.A. Le Bel in 1874. Dr Ramberg then examines the research programs in stereochemistry by Johannes Wislicenus, Arthur Hantzsch, Victor Meyer, Carl Bischoff, Emil Fischer and Alfred Werner, showing how the emergence of stereochemistry was a logical continuation of established research traditions in chemistry. In so doing, he also illustrates the novel and controversial characteristics of stereochemical ideas, especially the unprecedented use of mechanistic and dynamic principles in chemical explanation.

Download or read book Introduction to Stereochemistry written by Kurt Mislow and published by Courier Corporation. This book was released on 2012-06-11 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular shape, form, and symmetry play a central role in organic chemistry, and this text presents a brief introduction to the conceptual basis of stereochemistry. Its focus lies in the fundamentals of structural stereochemistry, rather than the dynamic aspects that are more relevant to reaction mechanisms. The three-part treatment deals with structure and symmetry, stereoisomerism, and the separation and configuration of stereoisomers. The first section reviews molecular architecture, relating empirical bonding geometries to the hybridization of the central carbon atom. Students receive a nonrigorous treatment of symmetry elements and point groups, with particular focus on the presence or absence of reflection symmetry. The second section classifies stereoisomers according to symmetry properties and to the nature of their barriers; it also discusses the dependence of optical activity on structure and concludes with an examination of topological isomerism. The third and final section explores the conceptual basis of asymmetric syntheses and kinetic resolutions. Each of the major sections features a series of exercises that reinforce and extend the preceding material, and answers are provided. Preface to the Dover edition. Answers to Exercises. Bibliography. Index.

Download or read book Taste Chemistry written by R.S. Shallenberger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: The object ofthis text is to examine, and elaborate on the meaning of the established premise that 'taste is a chemical sense.' In particular, the major effort is directed toward the degree to which chemical principles apply to phenomena associated with the inductive (recognition) phase of taste. A second objective is to describe the structure and properties of compounds with varying taste that allow decisions to be made with respect to the probable nature of the recognition chemistry for the different tastes, and the probable nature of the receptor(s) for those tastes. A final objective is to include appropriate interdisciplinary observations that have application to solving problems related to the chemical nature of taste. Taste is the most easily accessible chemical structure-biological activity relationship, and taste chemistry studies, i.e. the chemistry of sweetness, saltiness, sourness, and bitterness, have application to general biology, physiology, and pharmacology. Because it involves sensory perception, taste is also of interest to psychologists, and has application to the food and agricultural industries. The largest portion of the text is directed toward sweetness as, due to economic and other factors, the majority of the scientific studies are concerned with sweetness. The text begins with a prologue to describe the problems associated with the study of taste chemistry. Then, there is an introductory chapter to serve as an overview of the general interdisciplinary knowledge of the subject. It is followed by a chapter on the fundamental chemical principles that apply to taste induction chemistry.
