Problem of the Day #09 – Answer Key Deadline : 3:00 p.m., Friday, 6/20/08 LATE WORK WILL NOT BE ACCEPTED OR GRADED!!! This problem is worth a total of 20 raw points. In each part below, predict the products of the most likely Brønsted–Lowry acid–base reaction. Write the products in the appropriate boxes. If a product is a resonance hybrid, it is only necessary to draw one of the important contributing resonance structures. Please note that in Part (a) there is more than one type of proton in the acid on the left – assume that only the most acidic proton will react with the base. Similarly, in Part (b), assume that the most basic atom in the base on the left will abstract a proton from the acid. You may find it helpful to refer to Table 4.1 to help you judge relative acid or base strengths!!!

Unformatted text preview: In each part, indicate whether the equilibrium will favor the reactants or whether the equilibrium will favor the products by circling the appropriate choice. Once again, you may find it helpful to refer to Table 4.1 in your textbook to determine the position of the equilibrium.

    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.
