RCDs are the foundation for the EPF mechanisms we introduce to students. In introducing reactions, we can use limited resources to account for the outcome of chemical reactions without discussing thermodynamics and kinetics. Carbocation stability accounts 600 for the major and minor products formed in addition reactions. Thermodynamic stability explains why the Zaitsev product is formed with less sterically hindered, strong bases. Using limited resources provides students with a narrow understanding of all energy changes observed in the reaction. As instructors, we aim to provide a more complete picture outlining both kinetic and thermodynamic factors to enhance mechanistic reasoning skills. The 605 interplay of kinetics and thermodynamics appears throughout the curriculum, and by using a complete approach from the beginning, students will be more primed to analyze the kinetics and thermodynamics of more complex reactions such as the Diels-Alder reaction, the Michael addition, and the Wittig reaction-all of which require discussions of kinetic and thermodynamic control to explain why specific products are formed.
