Type: MCQ-conceptual-Medium-Class 12
[Co(C₂O₄)₃]³⁻ is a diamagnetic complex because
A
C₂O₄²⁻ is strong field ligand hence causes pairing of electrons
B
C₂O₄²⁻ is a bidentate ligand hence causes pairing of electrons
C
Co³⁺ is a strong central atom hence in all complexes of Co³⁺ electrons are paired
D
C₂O₄²⁻ is a strong field ligand hence causes splitting of d-orbitals
Correct Answer
Option A
Detailed Explanation
C₂O₄²⁻ is a strong field ligand that causes pairing of electrons in the d-orbitals, resulting in a diamagnetic complex.
