What is the maximum possible degree of degeneracy of the orbitals in 1,4-dichlorobenzene?
Which of the following transitions are electric-dipole allowed?(i) 2Π ↔ 2Π, (ii) 1Σ ↔ 1Σ, (iii) Σ ↔ Δ, (iv) Σ+ ↔ Σ−, (v) Σ+ ↔ Σ+.
Electronic excitation of a molecule may weaken or strengthen some bonds because bonding and antibonding characteristics differ between the HOMO and the LUMO. For example, a carbon–carbon bond in a linear polyene may have bonding character in the HOMO and antibonding character in the LUMO. Therefore, promotion of an electron from the HOMO to the LUMO weakens this carbon–carbon bond in the excited electronic state, relative to the ground electronic state. Consult Figs. 9E.2 and 9E.4 and discuss in detail any changes in bond order that accompany the π*←π ultraviolet absorptions in butadiene and benzene.
