- 8. Two structures of Lipitor (a drug used to lower cholesterol) are shown below. (a) Determine the absolute configuration of each indicated stereocenter. Fill in the correct circle. (b) Determine if the two structures are the same compound or stereoisomers. Fill in the correct circle. (a) НО. Carbon a HO O OH Carbon a: OR OS Carbon b H N Carbon b: R OS of H Carbon c: OR OS OH OH Carbon c F Carbon d: R OS OH Carbon d (b) The two structures are: O the same compound O stereoisomersarrow_forwardDraw the most stable chair conformation of mentol and label each substituents as axial or equatorial.arrow_forwardKetones react with alcohols to yield products called acetals. Why does the all-cis isomer of 4-tert-butyl-1,3-cyclohexanediol react readily with acetone and an acid catalyst to form an acetal, but other stereoisomers do not react? In formulating your answer, draw the more stable chair conformations of all four stereoisomers and the product acetal for each one.arrow_forward
- Following is a planar hexagon representation of L-fucose, a sugar component of the determinants of the A, B, O blood group typing. For more on this system of blood typing, see Chemical Connections: A, B, AB, and O Blood Group Substances in Chapter 25. (a) Draw the alternative chair conformations of L-fucose. (b) Which of them is more stable? Explain.arrow_forwardConsider 1-bromo-2-methylpropane and draw the following.
