Textbook Question
Chapter 4.SE, Problem 54AP
As mentioned in Problem 3-53, the statin drugs, such as simvastatin (Zocor), pravastatin (Pravachol), and atorvastatin (Lipitor) are the most widely prescribed drugs in the world.
(a) Are the two indicated bonds on simvastatin cis or trans?
(b) What are the cis/trans relationships among the three indicated bonds on pravastatin?
(c) Why can’t the three indicated bonds on atorvastatin be identified as cis or trans?

True or false: (a) The C¬C bonds in benzene are all the samelength and correspond to typical single C¬C bond lengths.(b) The C¬C bond in acetylene, HCCH, is longer than theaverage C¬C bond length in benzene.
Linoleic acid is an essential fatty acid found in many vegetable oils, such as soy, peanut, and cottonseed. A key structural feature of the molecule is the cis orientation around its two double bonds, where R1 and R2 represent two different groups that form the rest of the molecule.
(a) How many different compounds are possible, changing only the cis-trans arrangements around these two double bonds?
(b) How many are possible for a similar compound with three double bonds?
(a) Draw a skeletal structure of the anabolic steroid 4-androstene-3,17-dione, also called "andro,"
from the following description. Andro contains the tetracyclic steroid skeieton with carbonyl
groups at C3 and C17, a double bond between C4 and C5, and methyl groups bonded to C10
and C13. (b) Add wedges and dashes for all stereogenic centers with the following information:
the configuration at C10 is R, the configuration at C13 is S, and all substituents at ring fusions are
trans to each other.
