Is cis-4-methyl-2-pentene makes stable carbocation reacting with HCl than trans-4-methy-2-pentene?
4-chloro-2-methyl-2-pentene reacts with acetic acid (solvent), two substitution products are urmea, with the rearranged product predominating as shown in the diagram that follows. When small amounts of acetate ion are added to the reaction mixture, no increase in the rate is observed. Propose a mechanism that accounts for these results. Explain clearly why two products are formed (5 points) Minor Major
