3. Answer the following questions based on the reaction scheme below. a. Use wedged and dashed lines to draw the (2S,4R)-2-iodo-4-methoxypentane configuration of 2-iodo-4-methoxypentane in labeled box. b. Draw the product(s) of the nucleophilic addition reaction shown. Make sure to use wedged and dashed lines to clearly show the resulting stereochemistry at each chiral center. Label each chiral center as R or S. If there is more than one possible product, draw one in each box - if not, leave one box blank. c. Write the correct chemical name of each product(s) in the labeled boxes. 2-iodo-4- methoxypentane + NaOCH 3 K[C6H1310] Product Name: Product Name: d. Are all the product(s) chiral? If your answer is 'yes' write 'yes' in the box below. If your answer is 'no', provide an explanation in 3 sentences or less in the box below.

5. Our base choice determines how much of the original acid is left in solution at equilibrium. This will have significant consequences during our discussion of the Aldol and Claisen reactions. For each of the reactions below determine which is the most acidic proton in the first molecule. Assign a pKa value to at least the most acidic proton. Draw the expected conjugate base and acid. Assign a pKa value to the conjugate acid then determine the approximate position of the equilibrium (towards the starting material, towards the product, or near the middle - for example there would be a significant amount of starting material and product at equilibrium). Then predict the product of the reaction of the conjugate base with the reagent over the next arrow. An example is provided below. Alcohol 16 Lowest pKa =Most acidic Alcohol OH OH 16 OH NaOCH3 Br HO HOCH HO HO HO 16 10 Phenol 38 Amine Albuterol pKa 10 stronger acid pka 16 weaker acid = favored at equilibrium Difference in pKa values = 6…
Consider the Friedel-Crafts (FC) alkylation of N-phenylacetamide (shown below) in which a reaction with 1-chloropropane and AlCl3 produces two isomers of isopropyl N-phenylacetamide. 1. Draw the complete reaction mechanism for the formation of the ortho product (para is also formed). 2. Is this reaction faster or slower than the similar FC reaction starting with benzene (C6H6)? Explain why. 3. Explain why this reaction produces the ortho and para products (but not meta). Use your mechanism to help explain parts #2 and #3. Use additional drawings and words as needed.
