5. For each structure below, draw the best additional resonance structures. The mmber of additional resonance structures that you need to draw are indicated by the number of resonance arrows in each bracket for a given structure. It would be helpful to show my missing lone electrod pairs Don forget to include formal charge where applicable. (2pts for each correct resonance structure) Don't Completely understand the Resonance structure.
