Propose a reasonable stepwise mechanism, using curved arrow notation to show the flow of electrons, for the following reaction. Please have it computer done.. I've seen a lot of you guys use websites, I dont know why I keep getting the same like 2 people who want to do it by hand and then I can't even understand the hand writting when they write Carbon or Hydrogen or whatever other chemcial... Please just have it drawn using computer... I'm honestly just begging here... I've sent this question in so many times now. PLEASE I'M BEGGING YOU.... Just have it drawn out on a computer (I dont want it explained, I need a Drawing that shows all curbed arrows and electron flow)
