This book was released on 2012-12-06 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most organic molecules retain their integrity when dissolved, and even though in such cases the effects exerted by solvents are, in the language of the coordination chemist, of the "outer sphere" kind, the choice of solvent can be critical to the successful outcome of an operation or preparation. Solubilities of reactants and products must be taken into account, and even if the organic principals in the reactions retain their integrity, many of the reagents are electrolytes, and their state of aggregation will affect their reactivity. In testifying to the importance of understanding solute-solvent interactions I draw attention to a large class of inorganic species for which the involvement in the chemical and physical properties by the solvent is even more deeply seated. It is comprised by the large body of metal atoms in low oxidation states for which solvent molecules intervene as reagents. At the same time, because the ions carry charges, the effects arising from outer sphere interactions are usually greater than they are for neutral molecules. To cite an example: when FeCb(s) is dissolved in water to form a dilute - say O. OlO- solution there is a complete reorganization of the coordination sphere of the cation. Whereas in the solid each cation is surrounded by six chloride ions, in the solution the dominant form is [Fe(H20)6]3+ followed by [Fe(H20)sCI]2+, [Fe(H20)4CI2]+, etc. in rapidly decreasing abundance.

Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this volume, the first in a new series entitled Theoretical and Computational Chemistry, is to survey some effective approaches to understanding, describing and predicting ways in which solutes and solvents interact and the effects they have upon each other. The treatment of solute/solvent interactions that is presented emphasizes a synergism between theory and experiment. Data obtained experimentally are used as a basis for developing quantitative theoretical models that permit the correlation and interpretation of the data, and also provide a predictive capability. The latter being of course a key motivation for these efforts. Linear solvation energy relationships have been quite successful in this respect and accordingly receive considerable attention. Other effective approaches, including computational ones, are also being pursued, and are discussed in several chapters. This is an area that is continually evolving, and it is hoped that the present volume will convey a sense of its dynamic nature.

Download or read book The Chemical Physics of Solvation written by Revaz R. Dogonadze and published by Elsevier Science & Technology. This book was released on 1985 with total page 832 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of solvation as a concept which covers quite generally the interactions between a molecular solute particle and a macroscopic body of surrounding solvent is well recognized. Solvation plays a major role in the distribution of elements in the geo- and hydrosphere, and most chemical and biological processes involve solvated reactants and products, the electronic and molecular structure of which are strongly determined by solvation. This three-volume monograph has been written collectively by 50 authors from 14 countries who are specialists in different areas of solvation science. Part A deals with the theory of solvation; Part B is entirely devoted to spectroscopy of solvation; and Part C covers solvation phenomena in specific physical, chemical and biological systems. The volumes will be an invaluable reference source for physicists, physical chemists and biophysicists undertaking investigations into the diversified and fascinating areas of the physics and chemical physics of solvation at postgraduate and professional research levels.

Book excerpt: Solvents and Solvent Effects in Organic Chemistry Christian Reichardt From reviews of the first edition: This monograph can be recommended as a standard work to everyone who wants to be fully informed on the current knowledge of solvent effects in organic chemistry. It will be used successfully in research and industry to find the optimal reaction medium in the planning of a synthesis. Journal fúr praktische Chemie This is an extremely useful book which is well referenced (Chapter 5 alone lists 451 references) and it should find a place in the library of every practicing chemist who has occasion to call upon solvents to facilitate his reactions. Within hours of the book's arrival on my desk it had been confiscated by two of my students who have found it extremely useful. Journal of the American Chemical Society

Download or read book Local Solvent Environment Can Define Solute Chemical Identity Dynamics and Reactivity written by Devon Rose Widmer and published by . This book was released on 2020 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is it acceptable to assume that when a molecule is placed in solution, it retains the chemical identity and general behavior of its gas-phase counterpart? In this thesis, I explore this question through mixed quantum classical (MQC) molecular dynamics (MD) simulations of sodium dimer (Na2) and sodium dimer cation (Na2+) in liquid tetrahydrofuran (THF). Although most chemical reactions, particularly those relevant to biological systems, take place in the condensed phase, the solvent is generally thought of as a mere medium that holds the reactants and allows them to encounter each other via diffusion. Of course, there are scenarios where the solvent is known to influence the chemistry of the solute, but these cases are usually straightforward and are only thought about for a small subset of chemical reactions. However, no studies have yet described the local solvent environment as part of the chemical identity of the solute. In this thesis, I show that when there are even modest local specific interactions between a solute and solvent, the solvent controls the chemical identity of the solute, entirely changing the types of chemistry that can take place. In the specific case of an Na2 or Na2+ solute in liquid THF, I show that local solvent molecules actually integrate as part of the the solute's identity, thus, stabilizing the solute in multiple states that differ only in the number of solvent molecules associated with the solute's identity. These stable states, which can interconvert only by surmounting a large free energy barrier, behave as chemical species distinct not only from their gas-phase counterpart but also from each other. In addition, solvent interactions can also affect the dynamics of chemical reactions, such as photodissociation. Because the lowest energy excited state of gas-phase Na2+ is dissociative, this molecule makes an ideal basis for studies of photodissociation in the condensed phase, an important probe for understanding complex reaction dynamics. In this thesis, I show that when Na2+is photoexcited in liquid THF, the initial shape of the bonding electron is completely different than that of excited state Na2+ in the gas phase. This means that unlike its gas-phase counterpart, upon photoexcitation, the bond of Na2+ solvated in liquid THF does not immediately break. Instead, the electron must dynamically rotate into an orientation more favorable for dissociation. To investigate the dynamics of this process, I first pose a question fundamental to theoretical studies of the condensed phase: can a nonequilibrium system be understood through observation of the fluctuations of its equilibrium dynamics? This approximation, known as linear response (LR), is commonly assumed for condensed phase systems, but in this thesis I show that LR breaks down for the photodissociation of Na2+ in THF precisely because the local solvent environment experienced by the molecule varies between the equilibrium and nonequilibrium dynamics. In particular, I show that the solvent molecules associated with the solute's identity must shift from their preferred ground state positions to facilitate the rotation of the solute bonding electron into the position favorable for dissociation. Furthermore, in THF, the chemical identity of the solute can change during dissociation via the integration of new THF molecule's into the solute's identity. These processes consume most of the solute's dissociation energy, thus hindering its ability to fully dissociate. Thus, one cannot simply assume that a solute's chemical identity is retained in solution. In fact, when there are even modest solute--solvent interactions present, the local solvent environment actually controls the solute's chemical identity, and thus also its dynamics and reactivity.
