Answer 1

Hey mate ur answer is

(B) Square Planar

❤❤

Answer 2

Answer:

b. Square planar

Explanation:

The Ni 2+ is the d8 configuration, and since CN- is a strong field ligand, thus  all the eight electrons in the 3d orbital will be paired. The electron pairs are donated by CN-. The ligands fill one of the 3d orbitals and empty the 4s orbital and two of the other 4p orbitals such as the 4px and 4pz. This particular arrangement gives rise to a dsp2 hybrid orbital, and thus a square planar shape is expected.
