1 CHM 138H TUTORIAL 5 NOTE – MOLECULAR MODELS ARE HIGHLY RECOMMENDED! As described in the course outline, the tutorial quizzes will be based closely upon the textbook questions recommended below for this week's tutorial as well as those recommended in last week's tutorial. You should be able to do the questions below from the course textbook (J. McMurry, 7 th Edition). Please work through them in preparation for Tutorial 5. Chapter 9: 9.2-9.4, 9.6, 9.7, 9.9, 9.10, 9.12, 9.13, 9.15, 9.16, 9.20, 9.23, 9.24, 9.25, 9.26 (not syn/anti part), 9.31-9.35, 9.37, 9.38, 9.43-9.56, 9.63, 9.64, 9.65, 9.70-9.73, 9.75-9.80. Of the above, the following represent some of the better questions: 9.15, 9.33, 9.45, 9.47, 9.49, 9.50, 9.53, 9.56, 9.65, 9.75, 9.80. In addition, the following problems will be discussed: 1.

HO OH OH estriol Identify any stereocentres (chiral centres) present in estriol, and state how many stereoisomeric forms of the molecule exist. 2. Ibuprofen, the anti-inflammatory agent used in Advil and Motrin, is a chiral molecule. Only the ( S )-isomer is effective; the ( R )-isomer has no anti-inflammatory action. O HO Ibuprofen Identify the stereocentre in ibuprofen and draw its ( S )-isomer using 3D perspective at the stereocentre. 2 3. Shown below are Newman projections for ( R,R )-, ( S,S )- and ( R,S )-2,3-butanediol. a) Which is which? b) Which, if any, of the above Newman projections represent meso compounds? c) What is the stereochemical relationship between the different stereoisomers?
