Select from the list below, the correct description of the stereochemical outcome. Assume that the stereochemistry of the starting material is exactly as shown and that no other stereoisomers are involved as starting reagents. A pair of optically inactive meso- compounds are produced. A pair of optically active meso- compounds are produced. Two optically active diastereomers are produced. A meso-compound and a diastereomer (as a single enantiomer) are produced. A single meso- compound is produced. 8. H2/ Pto H. H3C...
