Question

For the complex [NiCl4]2-, write

(i) The IUPAC name.

(ii) The hybridization type.

(iii) The shape of the complex.

(Atomic no. of Ni = 28)

Answer

[NiCl4]2-

(i) IUPAC name = Tetrachloronickelate (II) ion

(ii) Hybridization of Ni in the complex [NiCl4]2- is sp3. The hybridisation scheme is shown in the following diagram.

 

Hence the hybridisation of Ni2+ in the complex is sp3

(iii) As the hybridization of Ni is sp3 so, shape of the complex is tetrahedral.
