Potassium ferrocyanide is an example of _____ complex
Updated On: Jun 3, 2024
- tetrahedral
- octahedral
- square planar
- linear
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
$K_{4}\left[F e(C N)_{6}\right] \rightleftharpoons 4 K^{+}+\left[F e(C N)_{6}\right]^{4-}$ is $+2$
$F e^{2+}-1 s^{2}, 2 s^{2} 2 p^{6}, 3 s^{2} 3 p^{6}, 4 s^{0} 4 p$
Since $CN ^{-}$is a strong field ligand, pairing occurs and the hybridisation of $\left[F e(C N)_{6}\right]^{4-}$ is $d^{2} s p^{3}$ and structure is octahedral.
$F e^{2+}-1 s^{2}, 2 s^{2} 2 p^{6}, 3 s^{2} 3 p^{6}, 4 s^{0} 4 p$
Since $CN ^{-}$is a strong field ligand, pairing occurs and the hybridisation of $\left[F e(C N)_{6}\right]^{4-}$ is $d^{2} s p^{3}$ and structure 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.
