Test: Quiz 4 over diels-alder, allyl, and benzene Question 1 1. Which of the following is a false statement? The allyl radical and anion have the same LUMO orbital. Propene is 17 times more acidic than propane. There are three unique orbitals resulting from the addition of three p orbitals. An example of the stability of the allyl radiation is the bromination reaction using N- bromosuccinimide with 1-methylcyclohexene. 10 points Question 2 1. Which of the following is a true statement? In an SN2 reaction, 3-bromo-1-butene is more reactive than 2-bromo-1-butene. 3-Chloro-2-methyl-1-propene is more reactive in an SN1 reaction the 2-chloro-2- methylpropane. For the addition of HX or X2 to a 1,3-butadiene system, a decreased reaction time and temperature favor the formation of the 1,2-addition product. Thermodynamic control is when the product distribution depends on the relative energies of the transition states leading to the products. 10 points Question 3 1. Which of the following is a false statement for the Diels-Alder reaction of conjugated dienes?

    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.
