The ECW model is a powerful tool for developing an understanding of donor-acceptor interactions. Most modern inorganic chemistry textbooks discuss the model's ability to correlate and predict enthalpies of adduct formation but overlook the application of the E and C parameters as a scale to analyze reactivity and spectroscopy. Furthermore, a survey of these textbooks indicate the authors are using parameters of different vintages. This article provides the teacher with the latest parameters as well as an update of the traditional uses of the ECW model and a discussion of some of the more important, often overlooked, applications of the model.
