stereoisomeerits
Stereoisomerism is a term used in chemistry to describe compounds that have the same molecular formula and connectivity of atoms but differ in the three-dimensional arrangement of those atoms. This variation can arise from stereogenic (chiral) centers or from restricted rotation about bonds. Stereoisomers share a formula and bonding pattern yet differ in spatial orientation, and most interconversions between them require breaking bonds rather than simple rotation. The term stereoisomerism is standard; “stereoisomeerits” is a common misspelling.
The main categories are enantiomers, diastereomers, and meso compounds. Enantiomers are non-superimposable mirror images and typically
Geometric isomerism, also called cis-trans or E/Z isomerism, arises from restricted rotation about a carbon–carbon double
Configurations are usually described using the Cahn-Ingold-Prelog (R/S) system for stereocenters and the E/Z system for
Applications of stereochemistry are broad, influencing drug design and activity, metabolism, polymer properties, and materials science.
