Abstract

Abstract : The Lewis acid/base interaction is a cornerstone of chemistry and is teaching material for every undergraduate chemistry student. Thus, a set of simple and intuitive rules to rationalize the strength of these interactions are desired. This article provides just that! The bond dissociation energy of X3 B–NY3 Lewis pairs increases along X, Y=F, Cl, Br, I, H because the Lewis acids become easier to pyramidalize, while the Lewis bases engage in stronger orbital interactions. Thus, it is shown that Lewis acid/base interaction depends not only on the attractive interactions but also on the energy required to deform them upon complexation.
