Pair of diastereomers
WebApr 14, 2024 · Enantiomers are pairs of stereoisomers that are non-superimposable mirror images of each other. Enantiomers have identical physical and chemical properties except for their interaction with polarized light and other chiral molecules. Enantiomers rotate the plane of polarized light equally but in opposite directions. Diastereomers: WebIn this helpful tutorial, you becomes learn about two types of stereoisomers: enantiomers and diastereomers, furthermore how they compare.

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). For n = 4, there are sixteen stereoisomers, or See more In stereochemistry, diastereomers (sometimes called diastereoisomers) are a type of stereoisomer. Diastereomers are defined as non-mirror image, non-identical stereoisomers. Hence, they occur when two or more … See more When the single bond between the two centres is free to rotate, cis/trans descriptors become invalid.
