Problem
In the optimal Lewis electron-dot structure of nitric oxide (NO), placement of the single unpaired electron is most consistent with which of the following?
(a) On the oxygen atom, primarily because the more electronegative oxygen stabilises the radical electron best.
(b) On the nitrogen atom, primarily because nitrogen is less electronegative than oxygen.
(c) Delocalised between nitrogen and oxygen owing to resonance that shares the unpaired electron equally over both atoms.
(d) On the nitrogen atom, because the more electronegative atom should hold additional electron density.
