MCQ
Select correct statement $(s)$ regarding $[Ni(DMG)_2]$ complex compound
  • A
    It acts as oxidising agent because $Ni^{2+}$ cation is having $E.A.N.$ $36$
  • B
    It is extra stabilized by hydrogen bonding
  • C
    It's $IUPAC$ name is Bis(dimethylglyoximato) nickelate $(II)$
  • ✓
    It's ligand contains two different donar sites
✓

Answer

Correct option: D.
It's ligand contains two different donar sites
d
The $IUPAC$ name of $K _2\left[ Cr ( CN )_2 O _2\left( O _2\right) NH _3\right]$ is Potassium amminedicyanodioxoperoxo chromate $(VI)$.The cation is potassium and the anion is the complex ion containing chromium metal in $+6$ oxidation state.

The oxidation state is written in roman numerals inside parenthesis.

The ligands $O$ and $O _2$ are oxo and peroxo respectively.

The prefix di indicates two.
