Benzene is the archetypical aromatic compound. It is planar, bond angles=120Âº, all carbon atoms in the ring are sp2 hybridized, and the pi-orbitals are occupied by 6 electrons. The aromatic heterocycle pyridine is similar to benzene, and is often used as a weak base for scavenging protons.
â¢ Although benzene is still drawn as a six-membered ring with alternating Ï bonds, in reality there is no equilibrium between the two different kinds of benzene molecules. â¢ Current descriptions of benzene are based on resonance and electron delocalization due to orbital overlap.t is planar. 3. All CâC bond lengths are equal. The Kekule kekulÃ© structures satisfy the first two criteria but not the, third because having three alternating Ï bonds means that benzene should have three short double bonds alternating with three longer single. bonds
