Answer 1

Answer:

The hybridization involved in complex [Ni(CN)₄]²⁻ is

(At. No. Ni = 28) [2015 RS]

(a) dsp²

(b) sp³

(c) d²sp²✔

(d) d²sp³

Answer 2

The hybridization involved in complex [Ni(CN)₄]²⁻ is (a) dsp².

• The outer electronic configuration of Ni  2+  ion is 3D`84S`0

• dsp² is a square planar, while others are octahedral and tetradedral

• One 3d, one 4s, and two 4p orbitals undergo dsp² hybridization.

• Four identical dsp² hybrid orbitals are occupied by four pairs of four cyanide ligands of electrons, thus forming [Ni(CN)₄]²⁻.
