4. For each of the structures shown below, use the curved-arrow formalism to draw two other reasonable
resonance structures.
The given structure is structure A. Draw arrows on structure A that would lead to a new resonance
structure, structure B. Draw arrows on structure B that would lead to structure C. Remember, each
structure (A, B, and C) must be unique structures, i.e. differ from one another.
