Interpretation:
In Figure D-10a and D-10b, every region of constructive interference and destructive interference between the HOMO and LUMO is to be labeled.
Concept introduction:
Molecular orbitals are constructed from the AOs of different atoms. When two atoms are brought close enough together (i.e., about a bond length apart), the AOs of one atom significantly overlap the AOs of the other atom, enabling them to undergo constructive and destructive interference, or mix, to produce new orbitals. When two orbitals overlap with the same phases, constructive interference takes place. When two orbitals overlap with the opposite phases, destructive interference takes place. Constructive interference results in a new orbital that is more stable than the σ bonding orbital, and destructive interference results in a new orbital that is less stable than the ρ atomic orbital. Constructive interference predominantly takes place in both Figure D-10a and Figure D-10b
