What is the meaning of Stereogenic?

describing a grouping of atoms in a molecule

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