Benzene Resonance Method MDCAT Quiz; One of the most vital concepts that an MDCAT student must learn is the Benzene Resonance Method. The concept of resonance is used to explain the structure of benzene, showing the delocalization of electrons over the six carbon atoms in the aromatic ring. Unlike most other compounds, where bonds are fixed, the electrons in benzene are evenly distributed throughout the ring, creating a hybrid of multiple structures. This delocalization results in the stabilization of the molecule, explaining its chemical properties—for instance, its inertness toward addition reactions. In fact, understanding resonance in benzene helps predict its reactivity in electrophilic substitution reactions, a frequent topic in the MDCAT exam.
