Question

Write the hybridization and shape of the following complexe : [Ni(CN)₄]^2–

^{(Atomic number : Co = 27, Ni = 28)}

Answer 1

The atomic number of Ni is 28 and its valence shell electronic configuration is 3d⁸ 4s².

Ni is in +2 oxidation state in the complex [Ni(CN)₄]^2–.

Hence, [Ni(CN)₄]^2– is dsp² hybridised and it is square planar in shape.
