NEET2009ChemistryCoordination CompoundsActual
Out of TiF ₆²⁻ and CoF ₆³⁻, Cu ₂ Cl ₂ and NiCl ₄²⁻ ( Z of Ti =22, Co =27, Cu =29, Ni =28) the colourless species are :
Options
- ACoF ₆³⁻ and NiCl ₄²⁻
- BTiF ₆²⁻ and CoF ₆³⁻
- CCu ₂ Cl ₂ and NiCl ₄²⁻
- DTiF ₆²⁻ and Cu ₂ Cl ₂
Correct answer
D. TiF ₆²⁻ and Cu ₂ Cl ₂
Step-by-step solution
In both TiF ₆²⁻ and Cu ₂ Cl ₂ , these no d - electrons or no unpaired electrons so, these are colourless.
