Show all important intermediates. OH CH3OH H2SO4 (cat) OCH3 OCH3 + I II b) (1 pt) Does this above reaction occur by an SN1 or SN2 mechanism? 2) (20 pts) Reaction Coordinate Diagrams a) (10 pts) On the graphs below draw two reaction coordinate diagrams accounting for the formation of product I and II from the reaction in question 1. Assume that both reactions a slightly exothermic. Indicate the reactants, intermediates, transition states and products on the graphs. I Energy Progress of reaction II Energy Progress of reaction b) (5 points) The reaction below occurs by a...
