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.
Jun 29, 2014. There are three antibonding orbitals in benzene. The six atomic p orbitals combine to form six molecular #Ï# orbitals. The three lowest orbitals #Ï_1#, #Ï_2#, and #Ï_3# are bonding orbitals. The six #Ï# electrons occupy these orbitals. The remaining orbitals #Ï_4^â³#, #Ï_5^â³#, and #Ï_6^â³# are antibonding orbitals.
