that the mechanism requires resonance steps. Thanks in advance!

CONCEPT QUESTIONS (10 POINTS) A recent publication reported a unique set of conditions used to facilitate the electrophilic aromatic nitration of phenol regioselectively and in high yield. OH H "H melamine - nitric aad (1.1 equivalents) p-TSA (0.06 equivalents) acetone 30 min room temperature NO; SO 0 N "H H 90% yield melamine ninacid melamonium nitrate A Use ChemDraw to construct your graphical answers and insert them below each question in this document Mechanism (5 pts) Draw the mechanism for this process, using proper arrows, formal charges, and label the rate-determining step (RDS). For this example, draw all important resonance structures for any reaction intermediate(s). Limiting Reagent (2 pts) Determine the limiting reagent of this reaction, and briefly explain the logic of this choice IR Spectroscopy (3 pts) Describe how IR Spectroscopy could be useful in demonstrating the conversion of phenol to 2-nitrophenol
