Unformatted text preview: emate, you form a racemate. When the starting material is enantiomerically pure or enriched (and therefore optically active) and reaction does not racemize stereocenter: Products enantiomerically pure or enriched and optically active. H C CH3 H CS CH3 Br
Cl2 Diastereomers Different environment Note: If you start from a racemate, you still form diastereomers, but they are racemic (not optically active). Stereoselectivity: Preferential formation of one stereoisomer over the other. Resolution: The Chemical Separation of Enantiomers From nature: The chiral "pool" Similar value coincidental...
