NEET Chemistry Isomerism in Complexes MCQ Question
Which of the following statements about isomerism in coordination compounds is correct?
Geometrical isomerism can occur in octahedral complexes with different arrangements of identical ligands.
Linkage isomerism involves the same ligands but different metal ions in a complex.
Optical isomerism occurs when a complex has no stereocenters and is superimposable on its mirror image.
Structural isomerism includes forms where the same ligands occupy different positions in the coordination sphere.
Correct Answer
Detailed Explanation
Geometrical isomerism arises in octahedral complexes with different arrangements of ligands, as described in the context. Linkage isomerism involves ambidentate ligands, not different metal ions. Optical isomerism requires stereocenters, which is not the case in option C. Structural isomerism does involve different bonding arrangements, but option D incorrectly implies it relates to ligand positioning.
