Question:
The IUPAC name of $K_3[Ir(C_2O_4)_3]$ is
The IUPAC name of $K_3[Ir(C_2O_4)_3]$ is
Updated On: Jul 28, 2022
- potassium trioxalatoidium(III)
- potassium trioxalaoiridate(III)
- potassium tris(oxalato)iridium(III)
- potassium tris(oxalato)iridate(III)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
IUPAC name of $K_3[Ir(C_2O_4)_3]$ is potassium trioxalatoiridate (III)
Let O.S. of Ir - $x$
$\therefore$ 3(+ 1) + $x$ + 3(-2) = 0
$ x$ = + 3
[O.S. of $K^+$ = +1. O.S. of $C2^{2-}_4$ = -2]

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.
