Question:

There are two dicarboxylic acids with the general formula HO2CCH==CHCO2H. One dicarboxylic acid is called maleic acid; the other is called fumaric acid. When treated with OsO4, followed by NaHSO3/H2O, maleic acid yields meso-tartaric acid and fumaric acid yields ±-tartaric acid. Show how this information allows one to write stereochemical formulas for maleic acid and fumaric acid.
