Updated On: May 12, 2024
- tetraamminedichlorocJ:iromium (I) nitrate
- dichlorotetraamminechromium (Ill) nitrate
- tetraamminedichlorochromium (IV) riitrate
- tetraamminedichlorochromium .(Ill) nitrate
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
IUPAC name of $\left[ CrCl _{2}\left( NH _{3}\right)_{4}\right] NO _{3}$ is
tetraamminedichlorochromium(III) nitrate.
The prefix tetra indicates the presence of $4$ ammonia ligands.
The prefix di indicate the presence of two chloro ligands.
The names of ligands are written in alphabetical order.
The oxidation state of chromium is written in roman numerals in parenthesis.

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.
