Vedclass · Answer

(D) The complex $[Ni(dmg)_2]$ (bis(dimethylglyoximato)nickel$(II)$) is a square planar complex.$1$. $Ni^{2+}$ reacts with dimethylglyoxime $(dmgH)$ in the presence of a base to form a rosy red precipitate,which is a standard test for $Ni^{2+}$.$2$. The hybridization of $Ni$ in this complex is $dsp^2$,resulting in a square planar geometry.$3$. The structure contains $2$ chelating rings formed by the ligand and the metal,and $2$ additional hydrogen-bonded rings,totaling $4$ rings.$4$. Each of the $2$ metal-ligand chelating rings is $5$-membered,not $6$-membered. Therefore,the statement that all rings are $6$-membered is incorrect.
