Question

Which of the following square planar complex does not show geometrical isomerism?

AA is symmetrical bidentate ligand
AB is unsymmetrical bidentate ligand
a and b are monodentate ligands

• A. $\left[M\right(AB)a_2{]}^{n\pm }$
• B. $\left[M\right(AA)a_2{]}^{n\pm }$
• C. $[M{a}_{3}b{]}^{n\pm }$
• D. All of the above

Answer 1

The correct option is D All of the above

Square planar complex shows geometrical isomerism, cis and trans.
In all given complex, the geometrical isomerism is not possible because there is only one possible geometrical arrangement.
