Equation for diastereomers

WebSwitching the configuration at least one stereocenter, but not all, yields diastereomers, non-superimposable stereoisomers that are not mirror images. The two molecules shown are diastereomers. A molecular modeling kit can prove extremely useful in visualizing the difference in such situations. ... Then, use the formula ... WebDiastereomers are stereoisomers not related through a reflection operation. [4] They are not mirror images of each other. These include meso compounds, cis – trans isomers, E-Z isomers, and non-enantiomeric …
