MCQ
Of the following which is diamagnetic in nature ?
- A$[CoF_6]^{3+}$
- B$[NiCl_4]^{2-}$
- C$[CuCl_4]^{2-}$
- ✓$[Ni(CN)_4]^{2-}$
✓
Answer
Correct option: D.
$[Ni(CN)_4]^{2-}$
d
$\left[ Ni ( CN )_4\right]^{2+}$ has $d ^8( Ni , 2+)$ which undergoes pairing to give (refer to image) $dsp ^2$ hybridisation and no unpaired electron so diamagnetic.
