11 Part II – Write your answers to all questions on this page in the space provided. If you use a pen, only blue or black ink is acceptable!!! PLEASE READ EACH QUESTION VERY CAREFULLY !!! 32. (12 points) Draw the indicated number of resonance structures in the large boxes provided. Be sure to show all lone pairs and nonzero formal charges ! (Note : If you think there are more than the indicated number of resonance structures, it is probably because you are writing structures that are relatively unimportant. The structures you draw in the boxes should be those of relatively greatest importance.) Place the symbol “ X ” in the small box located beneath the structure that is the relatively most important contributor to the “true” structure of the resonance hybrid. The most important structure might be one that is already given, or it might be one that you need to draw. Also note that you might end up needing to mark more than one small box with an “ X ”, if you think that 2 or more equivalent resonance structures are of relatively greater importance than the others drawn for that part! 33.
