On the аnswer sheet prоvided tо yоu for the exаm, or scrаp paper, complete all of the parts of the following question: Written Response Question 6 (9 pts): Introduction to synthesis. You now have the synthetic tools to ‘move’ functional groups such as double bonds and alkyl halides (I’m just reminding you that you know) as well as open and close rings. In the synthetic schemes below, on your answer sheet or scrap paper, fill in the appropriate reagents and/or products for the steps where they are missing. Click to Show Image Description A multi-step synthesis problem divided into three labeled sections, with dashed answer boxes labeled A through G indicating where students must supply either reagents, solvents, or products. The first section is labeled "Changing Stereochemistry:" and shows a two-step sequence. The starting material is a branched alcohol drawn as a zigzag carbon chain with an OH group attached via a bold wedge bond, indicating the hydroxyl projects toward the viewer and conveying specific stereochemistry at that carbon. A reaction arrow points to the right toward Box A, labeled "show reagents and or solvents," which is blank. A second arrow then points to Box B, labeled "show product of this step," which is also blank. A third arrow labeled NaCN above and DMF below points to a final product on the right consisting of a similarly branched carbon chain with a CN group attached via a dashed bond, indicating it projects away from the viewer. Lone pair dots are explicitly shown on the nitrogen of the CN group. The second section is labeled "Building a longer carbon structure:" and shows a two-step sequence. The starting material is a carbon chain containing an internal triple bond, shown as three parallel lines. A reaction arrow points to Box C, labeled "show reagents and or solvents," which is blank. A second arrow points to Box D, labeled "show product of this step," which is also blank. A third arrow labeled H₂O above and H₂SO₄ below points to a final product drawn as a branched carbon chain with a carbonyl group (C=O), representing a ketone. The third section contains two parts. The left part is labeled "Ring Closure:" and shows a starting material consisting of a branched carbon chain with a terminal double bond at one end and a bromine atom (Br) at the other end. A reaction arrow labeled H₂O above and H₂SO₄ below points to Box E, labeled "show product of this step," which is blank. The right part is labeled "Final step is Williamson Ether:" and shows an arrow from Box E leading to Box F, labeled "show reagents and or solvents," which is blank, followed by another arrow leading to Box G, labeled "show product of this step," which is also blank.
