Organic chemistry is closely related to our daily lives. We need to use carbon-containing compounds very frequently. In this module you learned how the reactivity of a reaction is related to both kinetic and thermodynamic factors. The energy barrier for a reaction to occur is called activation energy. A reaction may have competition between kinetic control and thermodynamic control. The former considers the reaction that has a lower activation energy that forms faster, while the latter concerns the more stable compound with a lower energy.
