TEST CODE:__01__
Read each question very carefully before writing and/or choosing your answer. This examination contains
two parts (PART I and PART II) worth a total of 100 pts . Part I consists of 20 questions (multiple
choices). Your score will be adjusted out of 200 pts on the Canvas gradebook. Enough space has been
provided for you to answer the questions in Part II. Your answer to Part II must be legible and all work
must be shown to receive full or partial credit. PLEASE DO NOT WRITE YOUR NAME OR
INITIALS BEYOND THIS PAGE.
PART I SCORE:_____________
PART II SCORE: _____________
TOTAL SCORE: _____________
ATTENTION: If you are caught cheating and having the following in your possession:
notes, cell phone, iPad, tablet, smart watches, and any electronic devices, which you do not
need for the exam, you will be given a “0” for the exam. Additionally, you will be reported
for Academic Dishonesty to the University.
, PART I (50 PTS)

rapidly?
(a) benzaldehyde (b) benzenesulfonic acid (c) iodobenzene

2. Provide the structure for (1E,3Z)-1-methoxy-2-methyl-1,3-pentadiene. Provide the structure for
(1E,3Z)-1-methoxy-2-methyl-1,3-pentadiene.
3. The Diels-Alder reaction is a concerted reaction; this means:
(a) a mixture of endo and exo products are formed.
(b) the reaction follows Markovnikov's rule.
(c) the reaction is highly endothermic.
(d) the products contain rings.
(e) all bond making and bond breaking occurs simultaneously.
4. Which of the following compounds is (are) a cumulated diene(s)?
(a) 5-methyl-2,3-heptadiene (b) 3-methyl-1,5-heptadiene (c) 2-methyl-2,4-heptadiene
(d) 4-methyl-1,4-heptadiene (e) 4-methyl-1,3-heptadiene

aromatic ring?
(a) 1.0-1.5 ppm (b) 2.0-3.0 ppm (c) 7.0-8.0 ppm (d) 4.5-5.5 ppm (e) 9.0-10.0 ppm
6. A thermodynamically controlled reaction will yield:
(a) the product whose formation requires the smallest free energy of activation.
(b) the most stable product.
(c) the product that can be formed in the fewest steps.
(d) the product that is formed at the fastest rate.
(e) None of these.
