Our purpose in eliminating completely the HAO and VSEPR models from introductory and organic chemistry is to avoid erroneous concepts about the distributions of electronic charge within molecules. We provide a general design to teach the basic curriculum of chemistry in the future without HAO and VSEPR.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen Para resolver el conflicto de enseñanza del modelo de orbitales atómicos híbridos (OAH) y el modelo de repulsión de pares de electrones de la capa de valencia (RPECV), se propone una forma original para la presentación de estructuras moleculares, iniciando con la resolución del inconveniente de mostrar pares de electrones sin usar los modelos de OAH y RPECV. Nuestra posición sobre la remoción completa de los modelos OAH y RPECV de los cursos introductorios de química y de química orgánica es para evitar inconsistencias en la distribución de electrons en moléculas. Finalmente, se prove un curriculum general para la enseñanza de los principios de la química en el futuro, en ausencia de OAH y RPECV.]]></p></abstract>
