Question

Find the difference between the number of optically active and optically inactive isomers of

Answer 1

1

Answer 2

The given structure represents a molecule with two identical chiral centers. For such a molecule, there are three stereoisomers: one pair of enantiomers (optically active) and one meso compound (optically inactive). The number of optically active isomers is 2 (the two enantiomers). The number of optically inactive isomers is 1 (the meso compound). The difference between the number of optically active and optically inactive isomers is 2 - 1 = 1.
