Curved arrows are used to illustrate the flow of electrons. Using the provided starting and product structures, draw the curved electron-pushing arrows for the following reaction or mechanistic steps. Be sure to account for all bond-breaking and bond-making steps. H HH Select to Add Arrows O..I H3O+ heat HH Select to Add Arrows H3O+ H heat I.O. Please select a drawing or reagent from the question area

Please give me idea why resonance is more reactive. I thought If resonance exists, it delocalizes more, and means less reactive

Please don't provide handwriting solution
