← ScienceWhich outcome results when an aromatic molecule with destabilized frontier orbitals undergoes single-electron reduction?
A)Increased radical anion stability✓
B)Decreased spin density delocalization
C)Increased LUMO energy level
D)Decreased HOMO-LUMO gap
💡 Explanation
Increased radical anion stability occurs because single-electron reduction populates the destabilized LUMO, which reduces the electron repulsions through increased orbital overlap, promoting the molecule's reduction. Therefore radical stabilty increases rather than delocalization reduction, because it is the anion that contains new electron added.
