Unformatted text preview: Chemistry 610A/618A Dr. Brent Iverson 2nd Exam Oct. 29, 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. RELAX, TAKE A DEEP BREATH, THINK ABOUT SOMETHING PEACEFUL AND BEGIN. NERVES AND PANIC ONLY HURT YOU, JUST ASK A GUY ON THE BOMB SQUAD, A SUSPENSION BRIDGE PAINTER OR A BALD GUY SHAVING HIS HEAD ! 10 9 8 7 6 5 4 3 2 (10) (16) (22) (18) (27) (21) (21) (23) (15) (20) (15) (208) 11 Total T Score 1 Page Points Signature_________________________ Pg 1 _____________(24) 1. (4 pts. each) Draw the structures indicated by each IUPAC name. trans-2-methyl-3-hexene (6Z)-2,6-dimethyl-2,6-nonadiene 2. (4 pts) For the structure, give an acceptable IUPAC name. (C)sp 3-(H)1s 3. (2 pts each) For the following molecule, in the circles write the hybridization state of the indicated atom, and in the box describe the indicated bond in terms of overlap of hybridized orbitals. For example, a correct answer in a box will be of the form: C CH 2 H CH 2 C C H H H C C CH 3 H H H 3 C C C H H H H C C H CH 3 H H 3 C C H H 3 C H 3 C C H H H C CH 3 H 3 C H 3 C C H H H 3 C 4. (15 pts. total) Rank the following species in terms of the stated property from 1 to 4 (or 3) as described, with intermediate numbers to rank the species of intermediate stability activity. Please make sure you know what we want, as you will get no credit if you get the numbers backwards! Signature_________________________ Pg 2 _____________(15) Stability of alkene: Place a 1 under the most stable (i.e. least reactive to H 2 /Pt) and a 4 under the least stable (i.e. most reactive to H 2 /Pt) Stability of carbocations: Place a 1 under the most stable carbocation and a 4 under the least stable carbocation. Relative Acidity: Place a 1 under the most acidic molecule and a 4 under the least acidic molecule. C C CH 3 CH 3 H H 3 C H C H H C H H H H C H H O H H C H H N H H H C H H C O O H Relative Acidity: Place a 1 under the most acidic molecule and a 3 under the least acidic molecule....
