1. What products are formed from a reaction flask that contains 2-bromopentane in ethanolic solution of sodium ethoxide? 2. What reaction pathway does the above reaction follow? 3. What is responsible for the major and minor products formed from the above reaction?

Show how to carry out the following transformation. Show all reagents and all molecules synthesized along the way. You do not have to use curved arrows. You are not allowed to use NBS/light or Br2/light.  You MUST use SOCl2/pyr.  for this drawing

Provide the mechansim using curved arrows of the reaction of p-t-butyl phenol treated with acetic anhydride in AlCl3. Include resonance stabilized intermediates and if more than one product is formed, label them as major, minor, etc. thank you for the help
