3. (18 pts) Testing out your synthesis arsenal; Having substitution, elimination, and electrophilic addition reactions under your belt, you now have a vast array of synthetic tools at your disposal! Starting from
isobutanol, provide a synthesis to yield each of the following transformations. I recommend reviewing
Problem-Solving Strategy “Organic Synthesis" at the end of Chapter 8. page 410. All transformation
product can be achieved from isobutanol in 2 to 4 reaction steps. Provide all reaction conditions for each
step of the synthesis. Transformation 2-9 involve an alkene intermediate along the synthetic path.
