- A$[Fe(CO)_5]$
- B$[Cr(CN)_6]^{-3}$
- ✓$[Mn_2(CO)_{10}]$
- D$[Fe(CN)_6]^{-4}$
$\mathrm{m}-2=0$
$\mathrm{m}=+2$
$\left(\mathrm{NH}_{3}\right)_{2} \Rightarrow$ Diammine
$\mathrm{Cl} \Rightarrow$ Chlorido.
$\mathrm{NO}_{2} \Rightarrow \mathrm{Nitrito}-\mathrm{N}$
So, IUPAC NAME:
diamminechloridonitrito-N-platinum(II)

Statement $I$: Aqueous solution of $K _2 Cr _2 O$, is preferred as a primary standard in volumetric analysis over $Na _2 Cr _2 O$, aqueous solution
Statement $II:$ $K _2 Cr _2 O$, has a higher solubility in water than $Na _2 Cr _2 O _7$
In the light of the above statements, choose the correct answer from the options given below:
Reason : Addition of non-volatile solute into solvent results into depression of freezing point of the solvent.
