1.397A 120 This resonance description lets us draw a more realistic representation of benzene,with 6 sp'hybrid carbons,each bonded to one hydrogen atom All the carbon-carbon bonds are of equal length,and all the bond angles are 120 Each carbon has an unhybridized p orbital,which lies perpendicular to the plane of the ring. These p orbitals each have 1 electron inside. There are therefore 6 electrons in the circle of p orbitals. (In simple terms,an aromatic compound can be defined as a cyclic compound,containing a certain number of conjugated double bonds,and being especially stable due to resonance).
