Vedclass · Accepted Answer

Geometrical isomerism is not observed in complexes of $C.N. = 4$ having tetrahedral geometry.

Vedclass · Answer

(A) $1$. Tetrahedral complexes with $C.N. = 4$ do not show geometrical isomerism because all positions are equivalent relative to each other.$2$. Square planar complexes of the type $[Ma_2b_2]$,$[Ma_2bc]$,and $[Mabcd]$ show geometrical isomerism.$3$. Complexes with formula $Ma_3b$ or $Mab_3$ do not show geometrical isomerism because there is only one possible arrangement.$4$. The complex $[Pt(Gly)_2]$ is a square planar complex where $Gly^-$ is an unsymmetrical bidentate ligand. It exists in two geometrical isomeric forms: $cis$ and $trans$. Therefore,statement $A$ is the only correct statement.
