Consider the six pz orbitals on carbon atoms (the pi system) of the benzene molecule (D6h symmetry). These may be treated as vector arrows pointing vertically above the plane of the six-membered ring.
A) work out the reducible representation for theses six pi-orbitals
B) reduce these to their irreducible components. (This gives the symmetry for the pi-molecular orbitals of benzene!)
