Solution
The correct option is B Cis-square planar The complex [Pt(NH3)2Cl2],pt−Cl has square planar geometry.
The isomer will be trans if the distance between two chlorine atoms is twice the C-Cl bond length.
The isomer will be cis if the distance between two chlorine atoms is less than twice the C-Cl bond length. This is the case in the given complex as 2.8oA<2×2oA
Thus the given complex is cis square planar complex.
