Benzene Structure MDCAT Quiz: Benzene Structure: A very important topic in organic chemistry and a must for MDCAT preparation. Benzene is a hydrocarbon, C₆H₆, with a planar, ring-shaped molecule where each of the six carbon atoms is bonded to a hydrogen atom. The structure shows resonance, with delocalization of electrons in the C–C bonds, which imparts stability to the molecule and makes it an aromatic compound. Due to this delocalization of electrons, benzene has certain unique properties; for example, it is resistant to addition reactions. The structure of benzene is important for understanding its behavior in chemical reactions, and it is always asked in the MDCAT exam.
