The hypothetical molecular square H4 is in the D4h point group.(a) Use the 4 1s-orbitals on the H’s involved in s-bonding with themetal as a basis for generating a reducible representation toproduce the symmetry-adapted molecular orbital combinations of theH4 square. (b) Reduce the representation to its irreduciblecomponents. (c) Sketch the resulting symmetry-adapted molecularorbitals and properly label each of them. Use the projectionoperator method. (d) Sketch the molecular orbital diagram showingthe relative energies of the resultant molecular orbitals. Therelative energies can be estimated using the number of nodespresent in each SALC.
