Question

Which of the following statement is true about the square planar complex, $\left[Pt\right(gly{)}_2]$?

• A. It shows both geometrical and optical isomerism
• B. It shows only geometrical isomerism
• C. It lacks both geometrical and optical isomerism
• D. It shows only optical isomerism

Answer 1

The correct option is B It shows only geometrical isomerism

Complex of type $\left[M\right(AB{)}_2]$ where, AB is unsymmetrical bidentate ligand shows geometrical isomerism.
Similar end of the two ligands at opposite position represent trans and at adjacent position represent cis.

The ligands and the cations are in same plane and the compound possess plane of symmetry. So it does not show optical isomerism.
