Quizplus · Accepted Answer

Complexes (c) and (d) are geometric isomers of each other because they have the same connectivity of ligands, but differ in their spatial arrangement due to the presence of a chiral center in the cyclooctadiene ligands. Complexes (a) and (f) have a different number of ligands and are not isomers of each other. Similarly, complexes (b) and (e) have the same connectivity and spatial arrangement of ligands, but different ligands altogether, so they are not geometric isomers. Therefore, the best choice is (c) and (d) as they are the only pair of complexes with the same connectivity and different spatial arrangement of ligands.
