5. 10 points Chose ONE of the following transformations and propose multi-step chemical syntheses for the product on the right from the starting material provided. All syntheses require more than one step. You can use any reagent with up to four carbons. Show the product for each step in your synthesis.

14) Propose a multistep synthesis of the following compound. All carbon atoms in the product must come cyclohexene and from alkanes, alkenes, alkynes, and alkyl halides that contain 3 or fewer carbon atoms. You can use other reagents as necessary. You do not have to draw any curved- arrow mechanisms. While you do not have the products of each synthetic step or explain your synthetic logic, you are strongly encouraged to in order to be eligible for more partial credit....
