TL;DR: In this paper, simple rules which all electronegative scales must obey and apply these to Pauling's scale were investigated and they were found to violate more than half of the elementary rules appropriate to χ scales.

Abstract: We first state simple rules which all electronegative scales must obey and apply these to Pauling's scale. Second, we investigate Pauling's bond energy−bond polarity equations and similar expressions that better reflect the additivity of energy. These relationships are then tested against many groups of molecules (including all of those previously tested by other research groups). Pauling χ is found to violate more than half of the elementary rules appropriate to χ scales. We also find that even the best form of the bond energy−bond polarity equation can only be satisfied by a very limited range of molecules and the form used by Pauling is only valid for a small number of bonds with low polarities.
