Which species undergo HOMO-LUMO transition from a gerade molecular orbital to an ungerade molecular orbital?
Options:(select one or more)
Answer:
A, D
Solution:
For O₂ and Br₂, the HOMO is πg* and the LUMO is σu*, giving a g → u transition.
N₂ and B₂ do not match this HOMO-LUMO symmetry change. Therefore A and D.
