Question:
IUPAC name of [Co(NH$_3$)$_4$(H$_2$O)Cl]Cl$_2$ is:
IUPAC name of [Co(NH$_3$)$_4$(H$_2$O)Cl]Cl$_2$ is:
Show Hint
Follow alphabetical order for ligands and include oxidation state of the central metal in Roman numerals. Counter ions go at the end.
Updated On: Oct 27, 2025
- Tetraammineaquachlorocobalt (III) dichloride
- Tetraamminechloroaquacobalt (III) chloride
- Tetraammineaquachlorocobalt (III) chloride
- Aquachlorotetraamminecobalt (III) chloride
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The central metal is cobalt (Co), oxidation state +3. Ligands are named alphabetically: ammine before aqua, then chloro. Counterions (Cl$^-$) are named last. So the correct order gives Tetraammineaquachlorocobalt (III) chloride.
