Abstract
PEARSON1 recently pointed out that Pauling's bond energy equation does not give reasonable values of the enthalpy changes for a series of reactions, and he has also stressed a number of pitfalls of Pauling's electronegativities. The principle of soft and hard acids and bases (SHAB), on the other hand, predicts the correct sign of ΔH for those reactions and the general chemical patterns mishandled by the simple electronegativity concept.
