Diastereomer - Wikipedia
There are many more pairs of diastereomers, because each of these configurations is a diastereomer with respect to every other configuration excluding its own enantiomer (for example, R,R,R is a diastereomer of R,R,S; R,S,R; and R,S,S).

Diastereomers can have different physical properties and reactivity. They have different melting points and boiling points and different densities. In order for diastereomer stereoisomers to occur, a compound must have two or more stereocenters.
Diastereomers - Definition, Characteristics, Properties and ...
We know stereoisomers that are not mirror images are called Diastereomers. They are either geometrical isomers or compounds containing two or more chiral centres. A Diastereomer is called erythro if its Fischer projection shows similar groups on the same side of the molecule.
Enantiomers vs. Diastereomers - ChemTalk
See which one of the compounds below is an enantiomer, diastereomer, or neither. Example One Solution. The compounds above are neither optical isomer. If you consider groups originating from the central atom, there are only three unique atoms. This does not fit the definition for a chiral center. Example Two Solution. The compounds above are ...

2024年9月23日 · To describe such a relationship, we need a new term: diastereomer. Diastereomers 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 ...

By definition a diastereomer is any stereoisomer that is not an enantiomer. Consider the possible optical isomers of 2,3-dichlorobutane. There are two chiral carbons, so there are #2^2 = 4# possible optical isomers. However, two of the structures are identical. They are the same meso compound. So there are only three isomers.
