Below are the pi molecular orbitals of benzene. Rank them in order of increasing energy based on the number of nodes. Consider that the blue color indicates one phase and the red color indicates the other phase of the orbital. Rank from lowest energy to highest energy. To rank items as equivalent, overlap them.

Question FOUR Consider the six pz orbitals on carbon atoms (the t-system) of the benzene molecule (Deh 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 these six π- orbitals. (B) Reduce these to their irreducible components. (This gives the symmetry for the t-molecular orbitals of benzene.)

The ordering of the energies of the pi-molecular orbitals of benzene is shown in Fig. 1. Those energies can be approximated by a two-dimensional particle-in-a-box, in which the energy values take a form very similar to those of a one-dimensional box: E_n_x, n_y = n_x^2 + n_y^2) h^2/8mL^2 where n_x and n_y take non-zero integer values. For this model, the first few derived energy levels, indexed by (n_x, n_y) pairs, are diagrammed in Fig. 2. Approximating benzene as a square,...
