The pairs of degenerate -antibonding molecular orbitals are there Six π- Molecular Orbitals (MO's) of Benzene.
A single nodal plane may be positioned in one of two ways in a cyclic pi system: through a bond or through an atom. This describes the second and third "floors" of benzene as being "degenerate," having two units each with the same energy.
According to molecular orbital theory, O2 has a total of 10 bonding electrons and 6 antibonding electrons, resulting in bond order 2.
In benzene, there are 15 bonding orbitals. Three C=C bonds, six C-C bonds, and six C-H bonds are present. Thus, there are now 16 bonding orbitals. The three sp2 orbitals on each carbon atom and the 1s orbitals on each hydrogen atom, according to molecular orbital theory, combine to generate the molecular orbitals.
