Concept explainers
(a)
Interpretation:
Why the greater contribution, from the second of the two resonance structures shown, is counterintuitive based on charge stability is to be explained.
Concept introduction:
The relative stabilities of resonance structures can be determined on the basis of charge stability. The structure with positive charge on less electronegative atom and negative charge on more electronegative atom is more stable. The most stable resonance structure contributes more to the resonance hybrid.
(b)
Interpretation:
The greater contribution from the second resonance structure is to be explained.
Concept introduction:
The most stable resonance structure contributes most to the hybrid.
Stability of a resonance structure depends on a number of factors. More the number of bonds, more the number of atoms that follow the octet or the duet rule and less the number of formal charge, the more stable the structure.
