10. (16 pts) a) Draw the 4 major resonance contributors for the molecule shown in the first box. Partially completed structures are provided as a time-saver. Do not generate any additional charges. b) Draw in all lone pairs of electrons and use arrows to show the movement of electrons within the structure. c) Place a checkmark in the small boxes of the three structures that contribute the most to the resonance hybrid. d) Circle all the nucleophilic atoms in the structure at the bottom of the page. 5 Initials the molecule below.

    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.
