The connection between some of the cis-isomer to any of one’s trans-isomer was diastereomers (A beneficial and C, A good and you may D, B and you will C, B and you will D)

It is very common there exists more than one chirality centers inside the an organic compound. To your exemplory instance of dos-bromo-3-chlorobutane lower than, there are two main chirality centers, C2 and you may C3. With each chirality center has actually one or two you’ll settings, Roentgen and S , the total amount of you’ll stereoisomers for this compound was five, with setup on C2 and C3 because RR , SS , RS and you may SR correspondingly.

In most cases, getting a compound provides letter chirality centers, the utmost amount of stereoisomers for the material is dos letter .

This new five stereoisomers regarding 2-bromo-3-chlorobutane add a couple of pairs out of enantiomers. Stereoisomers A beneficial and you will B was a set of low-superimposable mirror pictures, so that they is actually enantiomers.
