Draw the major product or products of each reaction. If the reaction is stereoselective, be certain that your structure(s) clearly indicate the correct stereochemistry. On the lines next to each reaction, indicate if the reaction likely proceeds by an Syl or Sx2 mechanism. H;C H F hexane CH;CH,Br CH; Br CH;OH e CN pentane Br CH; CH;CH, CH; H,0 C1
