Prepare a molecular orbital energy level diagram for SH2 molecule and answer the following questions:
a. How many group orbitals can be formed from two 1s orbitals of H atoms and what are their symmetries? Sketch a diagram for each group orbital.
b. List all symmetries of 3s orbital and three 3p orbitals of S atom.
c. Sketch a molecular orbital energy level, show the symmetry for each one, and indicate how each orbital is formed from the group orbital of 2H atoms and the atomic orbitals of S atom.
