Which among the following statements is true for $\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]$ ?
It is a neutral complex.
In this complex chlorine atoms are in ionization sphere
The coordination number of $\mathrm{Pt}$ in this complex is 2
The oxidation state of Pt in this complex is +4
Solution
$\mathrm{Pt}\left[\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right] \rightarrow$ It is a neutral complex. In this complex, chlorine atoms are in coordination sphere. Coordination number of $\mathrm{Pt}=4$, oxidation state of $\mathrm{Pt}+2$.
