Understanding Racemic Mixtures: Definition, Examples, and Separation Methods

Racemic refers to a mixture of two enantiomers, which are non-superimposable mirror images of each other. In this mixture, each enantiomer exists in equal amounts, and the racemic mixture has no net optical activity.

For example, when a chiral molecule is synthesized from a racemic precursor, the resulting mixture will be racemic, meaning that it will contain equal amounts of both enantiomers. Racemic mixtures can be separated into their individual enantiomers through various methods, such as chromatography or crystallization.

The term "racemic" is derived from the Latin word "racemus," which means "a cluster of grapes," and was first used in the context of chemistry by the French chemist Jean-Baptiste Dumas in 1835.
