Question:
A complex compound in which the oxidation number of a metal is zero is
A complex compound in which the oxidation number of a metal is zero is
Updated On: May 15, 2024
- $K_4[Fe(CN)_6]$
- $K_3[Fe(CN)_6]$
- $[Ni(CO)_4]$
- $[Pl(NH_3)_4]Cl_2$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
$CO$ is a neutral ligand, so the oxidation state of metal in metal carbonyls is always zero.
$\left[N i(C O)_{4}\right]$
$x+(0 \times)=0$
$x=0$
$\left[N i(C O)_{4}\right]$
$x+(0 \times)=0$
$x=0$

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.
