Give a detailed mechanism including all resonance isomers for intermediates (show electron flow) for the Friedel-Crafts reaction done in the lab. NOTE: It is likely the mechanism from reactants to only 1-t-butyl-2,5-dimethoxybenzene is on the blackboard in class. I want a complete mechanism showing all steps and resonance isomers for the synthesis of the dialkylated product!

for the reaction: acetaminophen + (NaOH/EtOH note: etoh is ethanol) and butyl iodide ---------------> 4-butoxyacetanilide a) The first step in this reaction is to reflux acetaminophen in a NaOH/EtOH solution, followed by the addition of butyl iodide. What is the purpose of using the NaOH/EtOH solution? Would the SN2 reaction still occur if the first step was not completed? Why or why not? b) Upon completion of the reaction (before filtration), an additional 4.0 mL of 1.0 M NaOH/EtOH was...
