1. Picture a two-dimensional sheet of graphite. 63 nm 731 The carbons re SP2 hybridized and the nonbonding electrons on each carbon can be modeled by free electrons traveling across the flat surface of the hexagons. The system above is 63 nm by 73 nm and has a total of 30 nonbonding electrons. (3 pts each) a. What model can you use to describe this system? b. What is the wavefunction for this system? (be specific) c. What are the energy levels of this system? d. Assuming two electrons can occupy an orbital, what is the Energy of the highest occupied molecular orbital? e. What is the Energy of the lowest unoccupied molecular orbital? f. What is the energy of a transition between these levels? g. What region of the electromagnetic spectrum is this? 2. The 4p radial wavefunction for the H-atom is (1/32√/15) x p(20 10p + p) x Zx e Using this information determine the radius of the nodes in units of Bohr radius for the 4p orbitals. (12 pts) 3. Describe the bonding, geometry and electronic distribution in formaldehyde. Label whatever theoretical model you are using. (12 points)
