Elimination Lab Discussion and Conclusion In this lab experiment, E1 and E2 reactions were compared, analyzed and explored using two different starting materials to successfully produce the same two products for each reaction. The E1 reaction utilizes 2-methyl-2-butanol as a starting material in sulfuric acid solvent. Since hydroxyl groups are generally poor leaving groups, the first step in this reaction proceeds with the oxygen in the hydroxyl group being protonated by a hydrogen from sulfuric acid. Since water is a very good leaving group in this case, it leaves readily, forming a stable tertiary carbocation intermediate. This intermediate is then attacked by HSO 4 - , who’s oxygen atom attacks the hydrogen adjacent to the sp2 carbon, which then allows a double bond to be formed at the more substituted position (2-methyl-2-butene), as well as the least substituted position (2-methyl-1-butene) in a 10:1 ratio. This ratio is

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
