Identify homoleptic complex from following.

Identify homoleptic complex from following.
  1. $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}$
  2. $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}$
  3. $\quad\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]$
  4. $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5 \mathrm{Cl}\right] \mathrm{SO}_4$

Solution

The complexes in which the metal ion is bound to only one type of ligand are called as homoleptic complexes. $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}$ is a homoleptic complex.
