For the complex ion[Co(en)(NH₃)₂(OH₂)Cl]²⁺, there are four possible geometric isomers.How many of these geometric isomers are optically active? A) none B) 3 C) all of them D) 1 E) 2

Question

Quizplus · Accepted Answer

The complex ion has a coordination number of 6, forming an octahedral complex. The presence of bidentate ligands (en) and monodentate ligands (Cl, OH) allows for geometric isomerism. Among the four geometric isomers, two will be mirror images of each other (due to the arrangement of the ligands around the central metal ion) and thus optically active. The other two isomers will be symmetrical and not optically active.
