Chemistry 310M/318M Dr. Brent Iverson 1st Midterm Sept. 28, 2005 NAME (Print): _____________________________ SIGNATURE: _____________________________ Please Note: This test may be a bit long, but there is a reason. I would like to give you a lot of little questions, so you can find ones you can answer and show me what you know, rather than just a few questions that may be testing the one thing you forgot. I recommend you look the exam over and answer the questions you are sure of first , then go back and try to figure out the rest. Also make sure to look at the point totals on the questions as a guide to help budget your time. Note: You must have your answers written in blue or black pen if you want a regrade!!!! Do not take this in red ink, as that is what we will use to grade it! Please print the first three letters of your last name in the three boxes Please answer the following before you begin: Have you been to a recitation section? ____________

Signature_________________________ Pg 2 _____________(17) 3 . (1 pt each) For the following TRUE and FALSE questions, CIRCLE ALL THE TRUE STATEMENTS. This is not meant to be tricky, but please read the statements carefully so that you do not make any careless errors. This page is worth a lot of points, so take your time. B. Resonance contributing structures do not represent equilibrating structures, rather the hybrid (blending) of them is the true molecular representation. C. When drawing resonance contributing structures you generally move atom nuclei and sigma bonds. D. When drawing resonance contributing structures, you should move pi bonds ( one bond of a double or triple bond) and lone pair electrons, not atom nuclei or sigma bonds. E. Arrows drawn on contributing structures show how electron pairs move. G. For unequal resonance contributing structures: full octets are favored, fewer charges are favored, and a
