Question:
Which from following complexes contains anionic ligand?
Which from following complexes contains anionic ligand?
Show Hint
Anionic ligands often end in "-o" (e.g., chloro, cyano, oxalato).
Updated On: Apr 30, 2026
- Tetraamminecopper (II) ion
- Pentaammineaquacobalt (III) iodide
- Tetracyanonickelate (II) ion
- Pentacarbonyliron(0)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Analysis
- (A) Ammine ($NH_3$) is a neutral ligand. - (B) Ammine and Aqua ($H_2O$) are neutral ligands. - (C) Cyano ($CN^-$) is an anionic ligand. - (D) Carbonyl ($CO$) is a neutral ligand.
Step 2: Conclusion
The tetracyanonickelate (II) ion contains the anionic cyanide ligand.
Final Answer: (C)
