Unformatted text preview: Chemistry 610A/618A Dr. Brent Iverson Final Dec. 13, 2003 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 10 9 8 7 6 5 4 3 2 (25) (16) (20) (26) (24) (19) (28) (17) (29) (30) (21) (10) (13) (13) (9) (28) (16) (344) 11 1 Page Points 16 17 Total T Score 12 13 14 15 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 Clavulanic Acid (A drug developed to overcome certain types of antibiotic resistance) Signature_________________________ Pg 1 _____________(25) 3. (5 pts) The most important question is chemistry is: ________________________________________________________________________________ N O H O O O O H H 2. (2 pts each) In the spaces provided write the hybridization state of the atoms indicated by the arrow. C C C H H H C H C H O 4. (1 pt each) Circle all of the true statements. Signature_________________________ Pg 2 _____________(16) A. More electronegative atoms attract the majority of electron density in a bond, thereby answering the most important question in chemistry, B. A sigma bond has the majority of electron density between atomic nuclei, while a pi bond has the majority of electron density above and below the bond axis. C. Constitutional isomers are molecules with the same molecular formula, but have the atoms connected differently to each other. D. The preferred staggered conformations of butane are the "gauche" conformations, rather than the "anti" conformation. E. Stereoisomers have the same connectivity (they are the same constitutional isomer), but the atoms are arranged differently in space. F. Dispersion forces are proportional to surface area , so the smaller the surface area of an alkane, the greater the attraction between molecules and the higher the boiling point....
