C) linkage
D) coordination
E) more than one of the above

Quizplus · Accepted Answer

Square planar complexes do not have any chiral centers, so optical isomerism is not possible. However, geometric isomerism can occur if there are two different groups or atoms attached to the same ligand. Linkage isomerism may occur if the ligand can coordinate through different atoms, and coordination isomerism may occur if the ligand can bind to the metal ion through different atoms or with different numbers of donor atoms.
