Delocalization of Lone-Pair Electrons into Antibonding Orbitals: Increased-Valence Structures, Mole be presented, with emphasis given to the relationship that exists between the “increased-valence” and the molecular orbital theory. Finally, by making particular use of the charge distribution for antibonding orbitals, expressions for atomic valencies will be deduced for “increased-valence” structures.

,Some Electron-Excess σ Bonded Systems,electrons of a Lewis structure into bonding or antibonding a orbitals. Some other examples will also be discussed in Chapter 20, where the theory will be presented in a slightly different form. However, the principles for both chapters are the same.

,Slater Determinants and Wave-Functions for “Increased-Valence” Structures,The Slater determinant theory of Section 3-7 will now be extended to construct wave-functions for “increased-valence” structures. Some of the theory for this Chapter will be used again in Chapters 20, 23 and 24.
