0 21. Tartaric acid is an important compound in the history of stereochemistry. Two naturally occurring forms are optically inactive. One form has a melting point of 206°C while the other melts at 140°C. The inactive tartaric acid which melts at 206°C can be separated into two optically active forms with [a] + 12º and [a] -12°, respectively. Both optically active forms melt at 170°C. Tartaric acid, which melts at 140°C, cannot be separated into optically active forms. a) Draw wedge dash diagrams of each structure on the drawing below. b) Identify the relationship between the various isomers. c) Can you be sure which tartaric acid in part bis dextrorotatory and which is levorotatory?
