Identify cationic complex from following.

Identify cationic complex from following.
  1. $\mathrm{Na}_3\left[\mathrm{AlF}_6\right]$
  2. $\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]$
  3. $\mathrm{K}_4\left[\mathrm{Fe}(\mathrm{CN})_6\right]$
  4. $\left[\mathrm{PtBr}_2\left(\mathrm{NH}_3\right)_4\right] \mathrm{Br}_2$

Solution

Cationic complexes: A complex in which the complex ion carries a net positive charge is called a cationic complex. Exa $\rightarrow\left[\mathrm{Pt} \mathrm{Br}_2\left(\mathrm{NH}_3\right)_4\right] \mathrm{Br}_2$ $\left[\mathrm{Pt} \mathrm{Br}_2\left(\mathrm{NH}_3\right)_4\right]^{2+}$ and $\mathrm{Br}$ Complex cation
