For each of the following species except ____,the electronic structure may be adequately described by two resonance formulas. A)O₃ B)SO₃^2- C)NO₂^- D)C₆H₆ E)SO₂

Question

Quizplus · Accepted Answer

The species in option B, which is the sulfate ion (SO4^2-), can be described by more than two resonance structures due to its tetrahedral geometry where each oxygen atom can share a double bond with the sulfur atom in different resonance structures. The other species have electronic structures that can be described by two resonance formulas, making option B the exception.
