2.) Draw a molecular orbital diagram for PH3 using the following orbitals. For P use the 3s, 3px, 3py, 3pz orbitals and for the protons use the following symmetry adapted linear combinations (SALCS). This problem is essentially the same as #3. Again, in addition to the MO diagram draw any orbitals you create, determine the symmetry of all orbitals, and label them as either sigma-bonding or sigma*. Don’t forget the electrons and show in your diagram the lone pair of...
