In chemistry, the ECW model is a semi-quantitative model that describes and predicts the strength of Lewis acid–Lewis base interactions. Many chemical reactions can be described as acid–base reactions, so models for such interactions are of potentially broad interest. The model initially assigned E and C parameters to each and every acid and base. The model was later expanded to the ECW model to cover reactions that have a constant energy term, W, which describes processes that precede the acid–base reaction. This quantitative model is often discussed with the qualitative HSAB theory, which also seeks to rationalize the behavior of diverse acids and bases.

(en) En química, el modelo ECW es un modelo semicuantitativo que describe y predice la fuerza de las interacciones de ácido Lewis - base de Lewis. Muchas reacciones químicas pueden describirse como reacciones ácido-base, por lo que los modelos para tales interacciones son de interés potencialmente amplio. El modelo asignó inicialmente los parámetros E y C a todos y cada uno de los ácidos y bases. El modelo se expandió posteriormente al modelo ECW para cubrir reacciones que tienen un término de energía constante, W, que describe los procesos que preceden a la reacción ácido-base. Este modelo cuantitativo se discute a menudo con la teoría cualitativa de HSAB, que también busca racionalizar el comportamiento de diversos ácidos y bases. (es) |
