9. (6 marks) For the molecule with the skeletal structure H-N-C-O, draw three resonance structures in the boxes provided below. Each resonance structure should have complete octets on as many

atoms as possible.Provide formal charges for all atoms (except if the charge on an atom is zero).Circle the resonance structure that should be the most important contributor to the overall resonance hybrid.If more than one structure is equally important, circle them both/all.
