Evening SN2 vs. E2 Homework Predict the major product(s) expected for each of the following reactions....
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...
3. Shown below are a series of reactions. Predict the major product for each of them. Remember, you will need to first decide whether the reaction occurs by an SN2, SN1, E2, or E1 before you can determine what the product will be. Label each as SN2, SN1, E2, or E1. Hint: First decide whether S2/E2 or S1/E1 is favored, and then decide whether the reaction pathway goes by a substitution or elimination reaction. SN2 / SN1 E2/E1 Na DMSO,rt...
termine whether each of the following reactions occur through an SN1, SN2, E1, or E2 mechanism. O E1 Br CH3SNat CH3CN (b) Br CH30 Na MeOH Oooo ooooo O-K (c) t-BuOH
Part II - Reactions (16 marks] Draw the expected major product(s) for each of the following reactions. Question Answer 8. 1. NaH OH ? 2. OTs 9. NBS ? major product 10. Nal Br ? Acetone Br 11. 1. NaNH2 H3C-CECH ? 2. OTS 12. OH Br NaOH ? cyclic compound 13. OH HBT ? 14. ? OH cat. H2SO4 H20 Room temp. 15. Br MeOH
please explain the work 1. Predict the major organic product for each of the following elimination reactions, and indicate whether each one occurs via the E1 or the E2 mechanism. Be sure to clearly indicate the proper stereochemical relationships between groups (if appropriate), and write the word "racemic" under any compound that is formed as a racemic mixture.

I need help with B. Professor's answer is SN2 but I thought it was E2 25. Draw the major product(s) expected for each reaction and also how each product is formed (options: SN1, SN2, E1, E2). Some reactions may occur via multiple pathways, in which case you should draw the major product for each pathway. Be sure to account for stereochemistry in your answers. If there is no reaction, write "No Reaction". Ez AL HACI 10 BuOK BuOH No SN...
4. (6 pts) Predict the major product for the following reactions. Remember to indicate stereochemistry, when appropriate. Unless otherwise noted you may assume that each reagent is available in excess. If no reaction is expected, write NR. 1 H2O OTS NaSH ü Nash DMSO Br QB CH,OH CH3OH
16. [10 points] (a) Draw the major product(s) expected for the reactions shown below. Indicate stereochemistry in the product when appropriate. (b) Classify each reaction as SN2, Sn 1, E2 or E1 or a combination of these if applicable. Br (a) + Xe K (CH3)3COH CI (b) K acetone (c) xi C2H5OH, A Br # Na Өс,н, + (d) OC2H5 C2H5OH (e) CH31 xo + K (CH3)3COH
Provide the MAJOR product(s) for the following reactions. SN2 and E2 reaction will only give one major product (the substitution of elimination product) major product (the substitution or elimin SOCI, Pyridine HCI (excess) Heat Oh ot H2SO4, H20 Nas DMF, 25 °C NaOH H20, 55 °C Br
