Bocknack CH 310M/318M Fall 2009 Graded Homework Problem #03 – Answer Key Deadline : 3:00 p.m., Thursday, 9/10/09 LATE WORK WILL NOT BE ACCEPTED OR GRADED!!! This problem is worth a total of 20 raw points. You’ll probably want to review the material in Section 1.8 of your textbook before tackling this problem!!! In each part below, draw the indicated number of additional resonance structures in the large boxes provided. Be sure to show all lone pairs and nonzero formal charges present in each resonance structure you draw! (Hint : Each additional structure should contain only one atom that has a nonzero formal charge!) 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

Unformatted text preview: 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! (a) (10 points) Draw 2 additional resonance structures. (b) (10 points) Draw 2 additional resonance structures.
