Bonding orbital energy diagrams

Figure 17.2 Schematic molecular orbital energy diagram for diatomic halogen molecules. (For F2 the order of the upper and 7T bonding MOs is inverted.).

Figure 6.6 shows the molecular orbital energy diagrams for a few homonudear diatomic molecules. The stability of the molecules can be estimated from the number of electrons occupying bonding orbitals compared with the number of electrons in the antibonding orbitals. (Antibonding orbitals are sometimes denoted with the subscript, as in 2jt. )... 

Use the appropriate molecular orbital energy diagram to write the electron configuration for each of the following calculate the bond order of each, and predict which would exist, (a) H2+ (b) H2 (c) H2- (d) H2 -... 

E2.32 The molecular orbital energy diagram for ammonia is shown in Figure 2.30. The interpretation given in the text was that the 2a) molecular orbital is almost nonbonding, so the electron configuration Iai le 2ai results in only three bonds ((2 + 4)/2 = 3). Since there are three N-H bonds, the average N-H bond order is I (3/3 = 1).

This equation is simply that for the photoelectric effect initially observed for emission from metallic surfaces, except that the work function term has been replaced by the energy required to remove an electron, i.e., the ionization potential. Such measurements allow the construction of molecular orbital energy diagrams directly from experimental data and provide a way of critically examining bonding theories without recourse to intuition.

On metal oxides weak hydrogen bond interactions can also evolve. The molecular orbital energy diagram for the gas-phase water molecule alone is shown in Fig. 6.2.
