Introducción a la interpretación de Ciclos Catalíticos: una metodología sencilla para estudiantes universitarios de segundo año
Contenido principal del artículo
Resumen
El conteo de electrones y la regla de los 18 electrones son herramientas importantes para la comunidad académica porque ofrecen información valiosa sobre un compuesto de coordinación, en particular para predecir su estabilidad y reactividad catalítica. En este trabajo, presentamos una metodología algebraica de fácil aplicación basada en el método de conteo covalente que permite al estudiante contar electrones mediante ecuaciones matemáticas. Además, proporciona información adicional sobre el compuesto de coordinación, incluyendo el número de electrones de valencia, el número de coordinación, el estado de oxidación y el número de electrones no enlazantes. A lo largo del manuscrito, mostramos cómo estos cuatro parámetros son útiles para reconocer los pasos elementales en catálisis, y se proporciona un árbol de decisiones para hacerlo. Finalmente, presentamos una metodología para interpretar ciclos catalíticos. Esta actividad se probó con más de 150 estudiantes de la Facultad de Química de la UNAM, con resultados alentadores en cuanto al conocimiento adquirido en el conteo de electrones e interpretación de ciclos catalíticos. Por lo tanto, creemos firmemente que esta estrategia puede ser muy útil para estudiantes universitarios, docentes e investigadores.
