Problem

Consider the anion below, which is a resonance hybrid. Only one important resonance structure is given – each additional important resonance structure only has one atom with a nonzero formal charge. Several of the carbon atoms in the given resonance structure are labeled. Which of these carbon atoms has a  negative formal charge on it in  any of the additional important resonance structures that are not shown? Pick the one choice below which best answers this question.

A. I only

B. II only

C. III only

D. IV only

E. I and III

F. II and IV

G. I and II

H. III and IV
