Question

Which complex shows geometrical isomerism?

Options

Choose one · Correct answer highlighted

[NiCl₄]^{2- [Co(NH₃)6]^{3+ [Fe(CN)6]^{4- [PtCl₂(NH₃)2] Correct

Explanation

[PtCl₂(NH₃)2] is square planar and can form cis and trans isomers, unlike tetrahedral or fully symmetric octahedral complexes. This follows from NCERT principle where relation explains outcome clearly for students.
