Question

(Ni(Cn)4)2_ coordination number​

Answer 1

Answer:

Gini Uni

Explanation:

Ni(CN)

4

]

2−

is a square planar geometry formed by dsp

2

hybridisation. [Ni(CN)

4

]

2−

is diamagnetic, so Ni

2+

ionhas3d^8$$ outer configuration with two unpaired electrons.

For the formation of the square planar structure by dsp

2

hybridisation, two unpaired d-electrons are paired up due to energy made available by the approach of ligands, making one of the 3d orbitals empty.
