Can u please solve these twl

B

For many reactions, at least two of the substitution or elimination mechanisms are in competition with one another. Each of the following pairs of reactants is an exception to this trend that goes almost exclusively by one of these four reaction mechanisms. For each reaction: Decide which reaction mechanism is most likely (SN1, SN2, E1, or E2) Draw the major product Briefly describe why these starting materials cannot or are unlikely to go by each of the other three reaction mechanisms.
