Topics and Learning Outcomes Heterocyclic Compounds  predict whether a molecule is aromatic  identify the basic nitrogen atoms in heterocyclic compounds  identify tautomers and predict their structures Shapes of Molecules: Stereochemistry  identify stereogenic centres in organic molecules  distinguish between different types of isomers, including enantiomers and diastereoisomers  use (R)- and (S)- descriptors to describe enantiomers and identify if a compound has (R)- or (S)- stereochemistry  predict the stereochemistry of compounds with two stereogenic centres  appreciate the role of chirality in nature and drug design Textbook and eBook References Heterocyclic Compounds - Section 25.1 Shapes of Molecules: Stereochemistry - Chapter 17 references are to Blackman, Bottle, Schmid, Mocerino and Wille, Chemistry, 2nd Edition, 2012 (John Wiley) Lecture Notes, Tutorial Worksheets & Answers and Suggested Exam Questions You need to login to eLearning to access lecture notes.
