PPT-14.5 Chiral Molecules

An object whose mirror image is identical to the original and can be superimposed on it is achiral Objects such as hands that have nonsuperimposable mirror images are chiral Learning Goal . 1. Chapter 5. Stereochemistry. Chiral Molecules. About The Authors. . These Powerpoint Lecture Slides were created and prepared by Professor William Tam and his wife Dr. Phillis Chang. . . Professor William Tam received his B.Sc. at the University of Hong Kong in 1990 and his Ph.D. at the University of Toronto (Canada) in 1995. He was an NSERC postdoctoral fellow at the Imperial College (UK) and at Harvard University (USA). He joined the Department of Chemistry at the University of Guelph (Ontario, Canada) in 1998 and is currently a Full Professor and Associate Chair in the department. Professor Tam has received several awards in research and teaching, and according to . Configuration.
