Benzene C6H6 is an aromatic compound with a hexagonal ring structure consisting of six carbon atoms and six hydrogen atoms. The carbon atoms are sp2 hybridized, and each carbon atom forms three sigma bonds: one with a hydrogen atom and two with adjacent carbon atoms. The remaining unhybridized p-orbital on each carbon atom contains one electron.There are two resonance structures for benzene, which can be represented as follows:1. Structure 1: The double bonds are located between C1-C2, C3-C4, and C5-C6.2. Structure 2: The double bonds are located between C2-C3, C4-C5, and C6-C1.These two resonance structures can be represented by a single structure with a circle inside the hexagon, indicating the delocalization of the pi electrons over all six carbon atoms.The delocalization of electrons in benzene occurs due to the overlapping of the p-orbitals of the carbon atoms, which creates a continuous pi electron cloud above and below the plane of the carbon atoms. This delocalization of electrons provides benzene with its characteristic stability and aromaticity.
