Using a symmetry-based approach, construct a complete molecularorbital diagram for OH2. (a) Indicate the HOMO and LUMO. (b) Draw arepresentation of the HOMO and LUMO. (c) If one were to react thiscation with another proton to give the dicationic species [H3O] +explain what would happen to the energies of the orbitals in theOH2 diagram after this reaction. Be specific about the key featuresregarding the M.O. diagram in the new cation. You do NOT need towrite a novel here – 3 or 4 sentences should be enough.Alternatively you can answer this part using a diagram – after all,a picture says a 1000 words.
