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...

What alkene is the major product formed from each alkyl halide in an El reaction? 4. Label the mechanism as SN2, SN1, E2 or El. You do not have to draw the product(s). CHO CH3-C-CH2-CH CH
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. For each reaction, draw the structure of the major product(s) including stereochemistry where appropriate. Fill n 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.
