- 6 and 6
- 5 and 6
- 5 and 3
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
en and ${C2O4^{2-}}$ are bidentate ligand. So coordination number of ${[Co(Cl)(en)2]Cl}$ is $5$ and ${K3[Al(C2O4)3]}$ is $6$.

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
