Question:
Identify neutral complex from following.
Identify neutral complex from following.
Show Hint
Neutral complexes do not have ionizable counter-ions outside the brackets.
Updated On: Jun 19, 2026
- Tetracyanonickelate (II) ion
- Sodiumhexafluoroaluminate (III)
- Triamminetrinitrocobalt (III)
- Tetraamminecopper (II) ion
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
A neutral complex has no net charge on the coordination sphere.
Step 2: Analysis
- (A) is an ion ($[Ni(CN)_4]^{2-}$). - (B) is an ionic salt ($Na_3[AlF_6]$). - (C) formula is $[Co(NH_3)_3(NO_2)_3]$. - Charge calc: $Co(+3) + 3 \times NH_3(0) + 3 \times NO_2(-1) = 3 - 3 = 0$.
Step 3: Conclusion
Hence, (C) is a neutral coordination compound. Final Answer: (C)
