Which among following complexes is a neutral complex?
Options
- A[ Co ( H ₂ O ) ( NH ₃ )₅ ] I ₃
- B[ Co ( NO ₂ )₃ ( NH ₃ )₃ ]
- CNa [ Co ( NO ₂ )₆ ]
- D[ Fe ( H ₂ O )₃( NCS ) ] Cl ₂
Correct answer
B. [ Co ( NO ₂ )₃ ( NH ₃ )₃ ]
Step-by-step solution
The complexes in which the coordination sphere does not carry any charge are called neutral complexes. [ Co ( NO ₂ )₃ ( NH ₃ )₃ ] is a neutral complex. [ Co ( H ₂ O ) ( NH ₃ )₅ ] I ₃ and [ Fe ( H ₂ O )₃ ( NCS ^2 ) ] Cl ₂ are cationic complexes whereas Na [ Co ( NO ₂ )₆ ] is an anionic complex.
