Question

[Pt(NH₃ )₄Cl₂ ]Br₂ complex can show: 

(A) Hydrated as well as ionization isomerism 

(B) Ionization as well as geometrical isomerism 

(C) Linkage as well as geometrical isomerism 

(D) Ionization as well as optical isomerism

Answer 1

(B) Ionization as well as geometrical isomerism

[pt(NH₃)₄Cl₂]Br₂ and [pt(NH₃)₄ Br₂]Cl₂ are ionization isomer.

∵ [pt(NH₃)₄Cl₂]Br₂ can form Cu & trans isomer, therefore it shows geometrical isomerism.

Both as and trans is omen have plane of symmetry  because of that they can not show optical isomerism.

And in [pt(NH₃)₄Cl₂]Br₂ , there is no ambidentate ligand so that if can not show linkage isomerism.

Hence, [pt(NH₃)₄Cl₂]Br₂ , shows only ionization as well as geometrical isomerism.
