5. Propose a reaction scheme to synthesize trans-3-octene (shown below) using only 1-butene as a source of C in the final structure. (Hint: You will need two equivalents of 1-butene.) You may use other reagents and solvents as needed. Show the product of each synthetic step. The expected yield of the product of a step that is used for subsequent steps should be > 75%. You do not need to show the mechanism. (Hint: Look to PS#1 if you get stuck!)

Draw visual representations of the steps below... 38. Follow the following reaction steps. Step 1: Identify the functional groups in the molecule below. Step 2: React the molecule above with NaBH4. Step 3: React the product in Step 2 with an acid catalyst (protonation) of the remaining carbonyl group. Step 4: Show intramolecular ring closure, followed by methoxy group leaving. regeneration of the carbonyl group, and loss of proton to methoxy group to make metha...

4. Synthesize the following compound. You may use benzene, acetylene, ethanol and any inorganic reagents. O₂N

Draw the structure of the product of each step in the three-step synthesis. Show the formal charges, if applicable. As a start, the benzene ring is drawn for you in each product. Although the first step produces a mixture of isomers, the para isomer is isolated as the sole product of interest and used in the second step. Give only the major product for the second and third steps. Br₂ FeBr HNO3 H2SO4 Br₂. FeBra Product 1 Product 2 Product 3 (para isomer) Draw product 1.
