Configurational Stereoisomer


Introduction

Organic chemistry, also known as “carbon chemistry”, is chemistry involving organic — or “carbon-based” — molecules. All life on Earth can be considered an expression of complex carbon chemistry. However, since lots of non-living things are carbon-based as well, organic chemistry isn't merely limited to biochemistry. Organic chemistry also deals with polymers, petroleum products, and much more.


Geometric Stereoisomers

Cis & Trans Isomers — differ by the orientation of bonds to non-chiral stereocenters. The cis & trans prefixes can be thought of as notation used for “simple” cases of E/Z isomerism.

E & Z Isomers — differ by the orientation of bonds to non-chiral stereocenters. E/Z notation works similarly to cis/trans notation, and can work for those cases but, unlike cis/trans notation, is also used for more complex molecules where prioritization of function groups must be considered.


Optical Stereoisomers

These are configurational stereoisomers that differ in the orientation of bonds to chiral stereocenters.

Diastereomers — differ in orientation around chiral centers.

Enantiomers — are exact mirror-images of one another.
