3. (continued) For each reaction, draw the structure of the major product(s) including stereochemistry where appropriate. Fill in the box below each arrow with the mechanism(s) that will be followed (SN1/E1, SN2, or E2). For SN1/E1 reactions, draw products for both. g) Сн,сн,он h) CH2O- Na CH3OH i) Me. Br A Eto Nat Me
16. Give the major product that you would expect to be formed in each of the following reactions. If you think there is no reaction write NR after the arrow. In each case give the mechanism (SN1, SN2, E1 or E2) by which the product is formed. Also indicate the correct stereochemistry when applicable. Both product and the mechanism should be correct to get credit. No partial credit. Nal -BuOK Acetone t-Buo NaSH DMF Br, H NaOMe DMSO MeOH,rt t-BuOH...
