On an Ionic Approximation to Chemical Bonding
نویسنده
چکیده
It is shown how previously reported bond energy equations (Van Hooydonk, 1973) can be re generated starting from the assumptions (i) that the valence-orbital energy of an element in a bond can be expressed as a function of its occupancy number (Iczkowski-Margrave, 1961) and (ii) that the potential around an atom in a bond vanishes as soon as its valence orbital is doubly occupied (Ferreira, 1963). The results are consistent with an ionic approximation to chemical bonding. A comparison of the approximations involved in the present theory with those in a semi-empirical LCAO —MO method (Klopman, 1964) is advanced.

On Drago's E-C Equation, Pearson's HSAB Rule and the Ionic Approximation to Chemical Bonding
An attempt is made to explain the E-C formalism for ionic interactions in terms of the ionic approximation to chemical bonding. Dravo's E-C equation is seen to be a first approximation to the bond energy equation as it is given by the ionic bonding approach. The meaning of the ratio C/E is discussed and its relation with the hardness and softness of interacting species, as these occur in Pearso...
متن کاملOn a Unified Potential Energy Function for Ionic and Non-ionic Bonds and the Question of Chemical Bonding
For 39 diatomic ionic and non-ionic molecules, the anomalous behaviour of the spectral parameters a e and wexe with respect to the bond type is reviewed. It is shown that on using a "universal" Sutherland parameter defined as A = ^kerc2/Dion, the anomalous behaviour disappears. Hard spectroscopic evidence is thus presented, for the first time to the author's knowledge, that just one bond type, ...
متن کاملThe Chemical Nature of Atomic Oxygen Adsorbed on Rh(111) and Pt(111): A Density Functional Study
The bonding of atomic oxygen on Pt(111) and Rh(111) was examined using density functional theory in order to understand their different chemical properties. The oxygen-surface interactions were modeled by bonding atomic oxygen to 10-atom clusters of Pt and Rh designed to model the (111) surface. Density functional theory was applied using the local density and generalized gradient approximation...
متن کاملVesicles and reverse vesicles of an ionic liquid in ionic liquids.
First evidence and the mechanism of formation of closed bilayer structures by a single chain amino acid ionic liquid (IL), L-proline isopropylester laurylsulfate in both hydrophilic and hydrophobic ILs, is reported. Such ionic self-assemblies are shown to be guided by fine balance of solvophobic effects and ionic arrangements via hydrogen bonding and electrostatic interactions.
متن کاملQuantum Chemical Modeling of Hydrogen Bonding in Ionic Liquids
Hydrogen bonding (H-bonding) is an important and very general phenomenon. H-bonding is part of the basis of life in DNA, key in controlling the properties of water and ice, and critical to modern applications such as crystal engineering, catalysis applications, pharmaceutical and agrochemical development. H-bonding also plays a significant role for many ionic liquids (IL), determining the secon...
