Assertion :

\left[\mathrm{Pt}(\mathrm{en})_2 \mathrm{Cl}_2\right]^{2+}

complex is less stable than

\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{2+}

complex.

Reason :

\left[\mathrm{Pt}(\mathrm{en})_2 \mathrm{Cl}_2\right]^{2+}

complex shows a chelate effect.

View answer and explanation

Correct option: D

Assertion is false, but Reason is true

Option D (Assertion is false, but Reason is true) is correct because the chelate effect makes [Pt(en)2Cl2]2+ more stable than [Pt(NH3)4Cl2]2+.
