Correct order of resonance energy of following compounds : – InterviewSolution

1.	Correct order of resonance energy of following compounds :
Answer» `IIgtIgtIVgtIII` `IIgtIVgtIgtIII` `IgtIIgtIIIgtIV` `IIgtIgtIIIgtIV` SOLUTION : I,II,III are AROMATIC due to delocalisation so more resonance energy than IV. Due to delocalisation- `I^(st)` get positive character on NITROGEN `II^(nd)` get positive character on sulfur. `III^(RD)` get positive character on oxygen. E.N: Oxygen GT Nitrogen gt Sulphur So resonance energy IIgtIgtIIIgtIV.
