For each of the following examples, (a) Draw a molecular orbital diagram. Include both the atomic orbitals that combine and the molecular orbitals that are formed. Clearly show the relative energies of all orbitals. Label all orbitals and show the appropriate number of electrons in the molecular orbitals. Give both labeling conventions (e.g. sigma2s and 1sigmag) for each of the molecular orbitals. You do not have to sketch the actual orbitals. (b) Give the bond order. (c) Indicate the effect...
