These questions are to help you find out how much you remember from your early college days...:)

 Write down the Lewis dot structures for the following molecules and Derive the shape of the above molecules using VSEPR.

Compare them with the optimized structures from molecular modelling

nitrite anion, sulfite anion, nitrous oxide, sulfur trioxide

2. Derive the MO energy level diagram for NO. Sketch the HOMO.  Verify the same after computing it in HYPERCHEM.
