Which type of isomerism is exhibited by the following complex?
\[
[Pt(NH_3)_2Cl_2]
\]
Show Hint
Solution and Explanation
geometrical isomerism.
Step 1: Possible arrangements. Two possible arrangements:
-
Cis form – Similar ligands adjacent to each other. -
Trans form – Similar ligands opposite to each other.
Step 2: Types of isomers.
- Cis-\([Pt(NH_3)_2Cl_2]\)
- Trans-\([Pt(NH_3)_2Cl_2]\)
Conclusion: \[ \therefore \text{The complex exhibits geometrical (cis–trans) isomerism. \]
