Please answer both.

4.(3) Identify which structures below are not resonance structures of the first structure, H ? S S 5. (5) The following structure is the anion of picric acid. Picric acid is a dangerous explosive. Picric acid is unusual in that it is much more acidic than other phenols. Draw the Lewis structure of the anion, showing all charges and lone pairs. Draw three other resonance structures where the negative charge has moved to each one of the NO: groups. You can use line angle structures for these, but draw out the NO, groups showing all the bonds and charges on the N and O atoms. Show electron pushing arrows. ON NO2 NO2
