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...
