Question:
Which of the following complex will show largest splitting of $d$-orbitals?
Which of the following complex will show largest splitting of $d$-orbitals?
Updated On: Aug 15, 2024
- $\left[ F _{ e }\left( C _2 O _4\right)_3\right]^{3-}$
- $\left[ F _{ e }( CN )_6\right]^{3-}$
- $\left[ F _{ e }\left( NH _3\right)_6\right]^{3+}$
- $\left[ F _{ e } F _6\right]^{3-}$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
CN is a strong field ligand so maximum splitting in d orbitals take place.
So, the correct option is (B): \(\left[ F _{ e }( CN )_6\right]^{3-}\)

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.
