The purpose of this video is to help second-year organic chemistry students review the concepts and questions that most frequently appear on standardized entrance exams, like the MCAT, DAT, PCAT, and GRE. In this video I'll share a personal anecdote about sign language the International House of Pancakes (IHOP). Then I'll continue by explaining chirality and teaching you how to assign R and S configurations to molecules that have stereocenters (also called chiral centers). I'll teach you how to assign molecules as being enantiomers or diastereomers, how to assign alkenes as being E or Z, and how to identify meso compounds. I'll also teach you how to calculate the number of possible stereoisomers that can exist for a certain structure, and I'll define the term "epimers." --Dr. Mike Christiansen from Utah State University.
