Question:
Indicate the complex ion which shows geometrical isomerism.
Indicate the complex ion which shows geometrical isomerism.
Show Hint
Geometrical isomerism occurs in square planar and octahedral complexes when two different ligands can be arranged in different spatial orientations.
Updated On: Apr 2, 2025
- \([Cr(H_2O)_4Cl_2]^+\)
- \([Pt(NH_3)_3Cl]_2^-\)
- \([Co(NH_3)_6]^{3+}\)
- \([Co(CN)(NC)]^{3-}\)
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding geometrical isomerism.
- Geometrical isomerism occurs in square planar and octahedral complexes when ligands can be arranged in cis and trans positions.
Step 2: Identifying the correct complex.
- \([Cr(H_2O)_4Cl_2]^+\) is an octahedral complex with two identical ligands (\( Cl^- \)), which can be cis or trans.
- Geometrical isomerism occurs in square planar and octahedral complexes when ligands can be arranged in cis and trans positions.
Step 2: Identifying the correct complex.
- \([Cr(H_2O)_4Cl_2]^+\) is an octahedral complex with two identical ligands (\( Cl^- \)), which can be cis or trans.
