Stereoisomers are isomeric molecules whose atomic connectivity is the same but whose atomic arrangement in space is different. Enantiomers Enantiomers are two stereoisomers that are related to each other by a reflection: they're mirror images of each other, which are non-superimposable. Human hands are a macroscopic example of stereoisomerism. Every stereogenic center in one has the opposite configuration in the other. Two compounds that are enantiomers of each other have the same physical prope… (More on Stereoisomerism)
