Pauling, bond energies

Results obtained using Pauling s bond energy terms. 

Using die values of electronegativity, Pauling further suggested that die fractional ionic contribution to the bond energy (FIG) is related to the electronegativities jca and xq in the A-B molecule and given by... 

Ketones are generally not polymerizable, despite claims that acetone can be polymerized at low temperatures (1 ). A simple explanation for the lack of polymerizability of ketones compared to vinyl monomers can be deduced from consideration of Pauling (Z) average bond energies as shown in Equations 1 and 2, where AHP°l(est) is the estimated enthalpy of polymerization based upon the difference in bond energies of the two single bonds formed in the polymer compared to the double bond in the monomer ... 

Pauling based electronegativity values on bond energies between atoms, but that is not the only way to approach the problem of the ability of atoms in a molecule to attract electrons. For example, the ease of removing an electron from an atom, the ionization potential, is related to its ability to attract electrons to itself. The electron affinity also gives a measure of the ability of an atom to hold on to an electron that it has gained. These atomic properties should therefore be related to the ability of an atom in a molecule to attract electrons. Therefore, it is natural to make use of these properties in an equation... 

What Pauling electronegativity is predicted for an element X if the ff-Xbond energy is 402 kj mol-1 The ff-ff bond energy is 432 kj mol-1 and the X-X bond energy is 335 kj mol-1. What would be the percent ionic character of the H-X bond If the molecular wave function is written as... 

Figure 5.35 displays a schematic energy-level diagram for each stationary species along the proton-transfer reaction coordinate. Although Pauling bond strengths... 

Electronegativity does not have a unit. The most widely used electronegativity scale today was derived by Linus Pauling. He used bond energy values in the preparation of this scale. 

The importance of the other major contributor to the bond energy, the IRE, can be illustrated in Pauling s (4) original terms. He showed that the reaction...
