The 9 pages that link to Meso compound, each with the reason it gives.
EnantiomerCompared with: Stereocenters alone do not guarantee that a molecule has an enantiomer.
Tartaric acidRelated: One tartaric acid stereoisomer is meso and therefore optically inactive.
RacemizationCompared with: A meso compound is optically inactive without being a racemate.
StereocenterCompared with: Its stereocenters do not make the whole molecule chiral.
