Vedclass · Answer

(B) The complex $[Ni(DMG)_2]$ is a square planar complex formed by $Ni^{2+}$ and two dimethylglyoximate $(DMG^-)$ ligands.$1$. The $DMG^-$ ligand is a bidentate ligand that coordinates through one nitrogen atom and one oxygen atom,but in the complex,the two $DMG^-$ ligands are held together by strong intramolecular hydrogen bonds between the $O-H$ and $O$ groups.$2$. This hydrogen bonding provides extra stability to the complex.$3$. The $IUPAC$ name is bis(dimethylglyoximato)nickel$(II)$,not nickelate$(II)$ as it is a neutral complex.$4$. The $EAN$ of $Ni$ in $[Ni(DMG)_2]$ is $28 - 2 + 2(4) = 34$,but this does not make it an oxidizing agent.$5$. Therefore,the most characteristic and correct statement is that it is extra-stabilized by hydrogen bonding.
