When $Ni^{+ 2}_{(aq.)} +$ Dimethyl glyoxime $NH_{4} OH$ complex $(X)$ is formed. What is the hybridisation of central metal of (X)

Options:

Answer:

Solution:

The reaction of Ni²⁺ with dimethylglyoxime (DMG) in the presence of NH₄OH forms a stable, square planar complex, bis(dimethylglyoximato)nickel(II). In this complex, Ni²⁺ has a $d^{8}$ configuration. DMG is a strong field ligand, causing pairing of electrons and forcing the Ni²⁺ to adopt $d s p^{2}$ hybridization to accommodate the four ligands in a square planar geometry.
