Examples of 'stereogenic' in a sentence
Meaning of "stereogenic"
stereogenic (adjective) - Stereogenic is a term used in chemistry to describe a molecule or compound that possesses a stereocenter, which is a carbon atom bonded to four different chemical groups. Stereogenic molecules exhibit chirality and optical isomerism

- describing a grouping of atoms in a molecule
- consisting of a central atom and four distinguishable ligands such that the interchange of any two leads to a stereoisomer
- consisting of four non-coplanar atoms such that rotation about the central bond leads to a stereoisomer
- consisting of a double bond with substituents which give rise to cis-trans isomerism
