11. For each of the following reactions, predict whether Syl or Sy2 will be the primary substitution mechanism. (Circle one) Br Nal in H2O - SN or SN2 CH,OH Sn1 or SN2 NaCN in DMSO Sn1 or S2 12. For the second reaction in question 11 (above), which do you think would react faster--the sec- ondary bromide or a secondary chloride (assuming the same reaction conditions)? (Circle one) Bromide Chloride Neither (rates are the same)
