Degree of Stabilization from Resonance [ENDORSED]

[SarahOMalley1D]

Hi! Is there a difference in the degree that different resonance structures stabilize a conjugate base? For example, would a compound with three bonding regions in resonance be more stable than a compound with two bonding regions in resonance? I think NO3- and NO2- would serve as a good example of this.

Yes, NO₃^- is more stable than NO₂^- as the negative charge is delocalized over three oxygen atoms.
As I discussed in class, the more charge is delocalized the more stable the compound.
