When evaluating resonance forms,an optimal structure is one that places positive formal charges on atoms with high electronegativity.

Question

Quizplus · Accepted Answer

An optimal resonance structure is one that distributes formal charges as evenly as possible, and considers the major contributors to the hybrid structure. While it is generally true that electronegative atoms tend to carry negative formal charges, positive formal charges can also be found on electronegative atoms in some cases. The key is to evaluate all possible resonance structures and consider their relative contributions to the overall hybrid structure.
