Draw the geometrical isomers of the given complex :…

The complex [Pt(en)2Cl2]2+ refers to a coordination compound of platinum (Pt) with two molecules of ethylenediamine (en) and two chloride ions (Cl) coordinated around the central platinum ion.

To draw the geometrical isomers of this complex, we need to consider the possible arrangements of ligands around the central platinum ion. Since both ethylenediamine (en) and chloride ions (Cl) are monodentate ligands, they can only coordinate through one atom.

Here are the possible geometrical isomers of the complex [Pt(en)2Cl2]2+:

1. Cis-Isomer: In the cis-isomer, both ethylenediamine ligands and both chloride ions are adjacent to each other.

   $\text{Cl–Pt–en–en–Pt–Cl}$

2. Trans-Isomer: In the trans-isomer, the ethylenediamine ligands and chloride ions are arranged across from each other.

   $\text{en–Pt–Cl–Cl–Pt–en}$

These are the two possible geometrical isomers of the complex [Pt(en)2Cl2]2+. In the cis-isomer, the ligands are adjacent to each other, while in the trans-isomer, the ligands are arranged across from each other.
