Stereoisomerism concept is studied in this chapter: chirality of chemical compounds, absolute configuration of a stereocenter, types of stereoisomers (enantiomers, diastereomers, meso compound), optical activity of stereoisomers, racemic mixture and enantiomeric excess. Chirality. Absolute Configuration R / S. To be diastereomers, a pair of molecules must have 2 or more chiral centers. B) To be diastereomers, a pair of molecules must have at least 1 chiral center. ... because they are enantiomers: C) because they both have the same absolute configuration: D) because there are no stereocenters present in either molecule: 25.Diastereomers (dia- stair -e-oh-mers) are stereoisomers that are not mirror images. Since we used the right-hand/left-hand analogy to describe the relationship between two enantiomers, we might extend the analogy by saying that the relationship between diastereomers is like that of hands from different people.Answer. 2.7: Isomerism Introduction is shared under a CC BY-NC-SA 4.0 license and was authored, remixed, and/or curated by LibreTexts.

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 ...19 Dec 2015 ... To understand the differences between enantiomers and diastereomers you need to be able to identify the chiral centers in the molecules then ...Figure 4.22 – Example of Enantiomers vs. Diastereomers. The number of possible stereoisomers increases exponentially as each stereocentre (or stereogenic element) is added. As a result of the broad definition of diastereomer, a molecule may have one enantiomer but many diastereomers. For example, this particular compound has eight ......
