What Are Stereoisomers?

Stereoisomers (stereoisomers) are the isomers produced by the different arrangement of atoms in the molecule in space. It can be divided into three kinds: cis-trans isomers, enantiomers and conformers. Can be divided into two major classes of enantiomers and diastereomers.

Configurational isomers are divided into two categories. Among them, the isomers caused by double bonds or single bonds of ring-forming carbon atoms that cannot rotate freely become geometric isomers, also known as cis-trans isomers. For example: cis-2-butene and trans-2-butene are a pair of geometric isomers. Cis-1,4-dimethylcyclohexane and trans-1,4-dimethylcyclohexane are also a pair of geometric isomers.

Stereoisomers with different optical rotation properties due to the absence of anti-axisymmetricity in the molecule are called optical isomers.
