Which is faster in Sn1 reaction?

Name each compound and decide which stereoisomer will react faster in an E2 elimination reaction. Explain your choice.

Predict the stereochemical outcome for the following E2 reaction. Draw only the major product of the reaction. NaOH ? Br

Draw the major organic product(s) for the following reaction.

Draw the products of each SN2 reaction and indicate the stereochemistry where appropriate. CH3 CCI a. b. H + -OCH3 + TOH C. d. CI + -OCH₂CH3 Br + CN

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

Which group is the best leaving group in a SN2 reaction? (The species below are after the leaving group has left the original alkyl compound.) H CH2 О
