Updated On: Jun 8, 2024
- $\left[M n\left(H_{2} O\right)_{6}\right]^{2+}$
- $\left[Cu\left(H_{2} O\right)_{6}\right]^{2+}$
- $\left[ Co \left( NH _{3}\right)_{6}\right]^{3+}$
- $\left[ Co \left( H _{2} O \right)_{6}\right]^{2+}$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
$\left[ Co \left( NH _{3}\right)_{6}\right]^{3+}$ is diamagnetic ion due to absence of unpaired electron. Its geometry is octahedral.

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.
