Which of the following complex compound exhibits geometrical isomerism ? — Coordination Compounds Chemistry Question

💡 Solution & Explanation

Step 1: Recall that the five d-orbitals of a free transition metal ion are degenerate (equal in energy). Step 2: According to Crystal Field Theory, the approach of any ligand field creates electrostatic repulsions that lift this degeneracy, causing the d-orbitals to split into levels of different energies. Step 3: This splitting and loss of degeneracy occur under any type of coordination environment, including weak, strong, mixed, or chelating ligand fields, making option (c) correct.
