Introduction to Chirality and Chiral Centers - Socratic

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 ...
