This is a tale about Algernon the Organic Chemist. In his laboratory one night, Algernon attempted to prepare an alcohol, 3-methyl-2- butanol (shown below) by the acid-catalyzed hydration of 3-methyl-1-butene. Well, guess what? His reaction made an alcohol in high yield, but it was NOT the alcohol he was trying to make. What alcohol did he make instead? [HINT: Mechanistically, a carbocation is formed. When a carbocation is especially unstable, what will it always try to do first? ] OH 3-methyl-2-butanol Select one: A. II B. I O C. IV D. III III НО OH H₂ö: 11 IV ? OH Ť OH

3) A common practice that organic chemists work on is a process known as retrosynthesis. In this a chemist will take known reactants and devise a synthetic pathway to produce the desired products using reactions that they know. As you proceed through organic chemistry you will be tasked with thinking about this process. How would you make the desired final product starting from the alkyne. It will take a couple of reactions. Please show the reagents necessary. And for your last step please show the arrow pushing. Starting material Br Product Br ...
