Oxyradical reactions: from bond-dissociation energies to reduction potentials.
Destructive radical reactions involve alkyl, alkoxyl and alkylperoxyl radicals, as well as alkylhydroperoxides. From bond energies the following reduction potentials vs NHE at neutral pH are derived: E0'(RO./ROH) = 1.6 V, E0'(ROO./ROOH) = 1.0 V, E0(ROOH/RO., H2O) = 1.9 V, and the two-electron reduction potential E0'(ROOH/ROH, H2O) = 1.7 V. Hydrogen abstraction from a bis-allylic methylene group...

15 صفحه اولBond dissociation energies
The bond dissociation energy (enthalpy) is also referred to as bond disruption energy, bond energy, bond strength, or binding energy (abbreviation: BDE, BE, or D) . It is defined as the standard enthalpy change of the following fission: R−X → R + X . The BDE, denoted by Do(R−X), is usually derived by the thermochemical equation, Do(R−X) = ∆fH o(R) + ∆fH o(X) – ∆fH o(RX) . The enthalpy of format...
متن کاملBond energies of molecular fragments to metal surfaces track their bond energies to H atoms.
The bond energy of molecular fragments to metal surfaces is of great fundamental importance, especially for understanding catalytic reactivity. Thus, the energies of adsorbed intermediates are routinely calculated to understand and even predict the activity of catalytic materials. By correlating our recent calorimetry measurements of the adiabatic bond dissociation enthalpies of three oxygen-bo...
متن کاملApplication of Electrochemistry to Determination of Transfer Gibbs Energies and Autoprotolysis Constants for Aqueous Mixtures of Dimethyl Sulfoxide
A practical potentiometric method was applied successfully to experimental electrochemical data in order to determine the autoprotolysis constants (pKap) of water + dimethyl sulfoxide mixtures containing 0-90 % of DMSO by volume at 25° C and 0.1 M ionic strength was maintained in each mixture by NaClO4 solution. The results indicated that water-DMSO mixtures are more basic media than pure water...
