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...

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...

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.
