Unformatted text preview: Chemistry 310M/318M Dr. Brent Iverson Final Dec. 19, 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. I recommend saving questions marked "challenge" until you are finished with all of the other questions. Note: You must have your answers written in pen if you want a regrade!!!! Please print the first three letters of your last name in the three boxes For synthesis problems GO FOR PARTIAL CREDIT EVEN IF YOU DO NOT KNOW THE ENTIRE ANSWER!!!WRITE DOWN WHAT YOU DO KNOW IS IN THE REACTION SEQUENCE SOMEWHERE. YOU WILL GET PARTIAL CREDIT IF IT IS CORRECT 14 13 12 11 10 9 8 7 6 15 5 20 21 Total 16 17 18 19 4 3 2 (31) (30) (24) (16) (17) (18) (18) (9) (15) (20) (20) (34) (33) (27) (11) (14) (10) (19) (13) (8) (21) (408) 1 Page Points T Score HW Use this page to write down your roadmap if you would like. 1. (2 pts each) In the spaces provided, indicate the type of bond, and the hybridized orbitals that overlap to form the bond. For example, one answer could be: (C)sp 3-(H)1s A lipid (fat) (a friendly reminder to eat smart this holiday season) Signature_________________________ Pg 1 _____________(31) O O O O O O N C C O H H H This functional group is called an isocyanate. 2. (5 pts) The most important question is chemistry is: ________________________________________________________________________________ (C)sp 3-(C)sp 3 (C)sp 2-(O)sp 3 (C)sp 2-(O)sp 2 (C)2p-(O)2p (C)sp 2-(C)sp 2 (C)2p-(C)2p (C)sp-(O)sp 2 (C)2p-(O)2p (C)sp 3-(N)sp 2 Where are the electrons? NOTICE THIS (2 pts each) For the following molecule, state the hybridization state of each atom indicated by the arrow. H 2 C CH C C CH 2 H 3 C CH 3 sp 3 sp 2 sp 2 sp 2 O Signature_________________________ Pg 2 _____________(30) 3. (2 pts each) Circle all the True statements. (Do not circle any false statements) You may notice these resemble Rules of the Day! These are worth a lot of points so please take your time and be careful. Do not second guess yourself as we are not trying to trick you. A.) In a covalent bond, the more electronegative atom attracts more of the electron density. B.) The VSEPR model assumes areas of electron density repel each other, so areas of electron density are distributed around an atom to be as far apart as possible....
