Diastereomers vs enantiomers examples

If a molecule contains two asymmetric centers, there are up to four possible configurations, and they cannot all be non-superposable mirror images of each other. The possibilities for different isomers continue to multiply as more stereocenters are added to a molecule. In general, the number of stereoisomers of a molecule can be determined by calculating 2 , where n = the number of chiral centers in the molecule. This holds true except in cases where the molecule has Web1. Which of these molecules are diastereomers of each other? 2. What is the difference between enantiomers and diastereomers?

WebExplanation: Diastereomers are compounds that contain two or more chiral centres and are not mirror images of each other. For example, the aldopentoses each contain three chiral centres. Thus, D-ribose is a diastereomer of D-arabinose, D-xylose, and D-lyxose. Epimers are diastereomers that contain more than one chiral center but differ from ...
