Hydrogen anion solvation

This classification is not rigid. Protic solvents are particularly good anion solvators due to their hydrogen-bonding ability (Symons and Thomas, 1981). The observation... 

At the ambient temperature barrier of that size is easily overcome and, therefore, attachment of excess electron to the GC base pair (incorporated in DNA as the Watson-Crick configuration) should end up with the neutral radical of hydrogenated cytosine solvated by the anion of deprotonated guanine. Proton transfer induced by electron attachment has already been suggested in the past by the group of Sevilla within their computational [76] and experimental studies [77],... 

The strong anion-solvating power of water, methanol, and many other hydroxylic solvents is due to hydrogen bond formation. 

A comparison of anion solvation by methanol, a protic solvent, and dimethylformamide, a dipolar aprotic solvent, is instructive. The electrostatic contribution, d/i , to the Gibbs free energy of solvation per mole of an ion is sometimes estimated quite successfully (Stokes, 1964) from the Bom model, in which a charged sphere of radius r is transferred from vacuum to a medium of uniform dielectric constant, c. The Bom equation (17) suggests that an anion should be similarly solvated in methanol and in DMF, because these solvents have effectively the same dielectric constant (33-36). The Born equation makes no allowance for chemical interactions, such as hydrogen-bonding and mutual...
