With explanation please -- thanks! 9. (30 pts) Predict whether the following conditions would mainly proceed via an SN2, SN1, E2, or E1 mechanism (write your answer into box on left). Draw the major product (including enatiomer wher appropriate) in each reaction and show stereochemistry (where appropriate).

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...
