Question:
$ C{{N}^{-}} $ is strong field ligand. This is due to the fact that
$ C{{N}^{-}} $ is strong field ligand. This is due to the fact that
Updated On: Jul 12, 2022
- it carries negative charge.
- it is a pseudohalide
- it can accept electrons from metal species
- it forms high spin complexes with metal species
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
$ C{{N}^{-}} $ is strong field ligand because it is an example of pseudohalide. Pseudohalide ions are stronger coordinating ligands and they have the ability to form a bond and $ \pi $ bond.

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.
