2. (28 points total) Presented here is the MO Diagram for the trigonal planar complex BH3. a. The point group is Dah; draw and label the molecule with Cartesian coordinates that best describe this molecule? (4 pts) b. Make a reducible representation () that describe the three H ls orbitals. (6 pts) c. The is for the three H atoms reduces to Ai' and E'. Fill in the MO diagram and label each MO as bonding, antibonding or nonbonding. (12 pts) d. What is the bond order? (4 pts) e. Designate which MO is the HOMO and which is the LUMO. (2 pts) D3 30, 1 Az! - ...) 203 25 30, 1 1 1 1 1 1 1 2 1 -1 -1 0 1 -1 -1 0 R: L.)
