Bond Length, Polarity, and Electronegativity

Abstract

The question of bond shortening in heteronuclear bonds is reconsidered in the light of the results obtained with an ionic approximation to chemical bonding. A definite answer can only be given when the relation between an elements valence-state-ionization energy and -electron affinity is understood. Two empirical bond shortening relations, i. e. those of Schomaker-Stevenson and Huggins, are shown to be incompatible. © 1974, Walter de Gruyter. All rights reserved.
