Consider the octahedral complex [M(AB)₂cd], where AB is an unsymmetrical bidentate chelate and c, d are different achiral monodentate ligands. How many of its geometrical isomers are optically active?

Question

Consider the octahedral complex [M(AB)₂cd], where AB is an unsymmetrical bidentate chelate and c, d are different achiral monodentate ligands. How many of its geometrical isomers are optically active? Count each geometrical isomer once, not each enantiomer.

TestHub · Accepted Answer

[M(AB)₂cd] has 6 geometrical isomers and 11 stereoisomers in total. If a isomers are achiral and b are chiral, a + b = 6 and a + 2b = 11, so b = 5 and a = 1. Five geometrical isomers are optically active.
