Explanation: Meso-tartaric acid is an optically inactive molecule with a chiral carbon atom. Its mirror-image enantiomer, (S,S)-tartaric acid, as well its diastereoisomer, (2R,3S)-tartaric acid, can also be synthesized. Naturally occurring tartaric acid is chiral, and is a useful raw material in organic chemical synthesis.The naturally occurring form of the acid is dextrotartaric acid or L-(+)-tartaric acid (obsolete name d-tartaric acid).Because it is available naturally, it is slightly cheaper than its enantiomer and the meso isomer.The dextro and levo prefixes are archaic terms. 1. read less.
