Question

Among the following options, select the option in which each complex in Set-I shows geometrical isomerism and the two complexes in Set-II are ionization isomers of each other.
[$\mathrm{en}=\mathrm{H}_{2}\mathrm{NCH}_{2}\mathrm{CH}_{2}\mathrm{NH}_{2}$]

Accepted Answer

(C) Set-I: $[\mathrm{Co}(\mathrm{NH}_{3})_{3}(\mathrm{NO}_{2})_{3}]$ and $[\mathrm{Co}(\mathrm{en})_{2}\mathrm{Cl}_{2}]$
Set-II: $[\mathrm{Co}(\mathrm{NH}_{3})_{5}\mathrm{Cl}]\mathrm{SO}_{4}$ and $[\mathrm{Co}(\mathrm{NH}_{3})_{5}(\mathrm{SO}_{4})]\mathrm{Cl}$

Answer

(A) Set-I: $[\mathrm{Ni}(\mathrm{CO})_{4}]$ and $[\mathrm{PdCl}_{2}(\mathrm{PPh}_{3})_{2}]$
Set-II: $[\mathrm{Co}(\mathrm{NH}_{3})_{5}\mathrm{Cl}]\mathrm{SO}_{4}$ and $[\mathrm{Co}(\mathrm{NH}_{3})_{5}(\mathrm{SO}_{4})]\mathrm{Cl}$

Answer

(B) Set-I: $[\mathrm{Co}(\mathrm{en})(\mathrm{NH}_{3})_{2}\mathrm{Cl}_{2}]$ and $[\mathrm{PdCl}_{2}(\mathrm{PPh}_{3})_{2}]$
Set-II: $[\mathrm{Co}(\mathrm{NH}_{3})_{6}][\mathrm{Cr}(\mathrm{CN})_{6}]$ and $[\mathrm{Cr}(\mathrm{NH}_{3})_{6}][\mathrm{Co}(\mathrm{CN})_{6}]$

Answer

(D) Set-I: $[\mathrm{Cr}(\mathrm{NH}_{3})_{5}\mathrm{Cl}]\mathrm{Cl}_{2}$ and $[\mathrm{Co}(\mathrm{en})(\mathrm{NH}_{3})_{2}\mathrm{Cl}_{2}]$
Set-II: $[\mathrm{Cr}(\mathrm{H}_{2}\mathrm{O})_{6}]\mathrm{Cl}_{3}$ and $[\mathrm{Cr}(\mathrm{H}_{2}\mathrm{O})_{5}\mathrm{Cl}]\mathrm{Cl}_{2}\cdot\mathrm{H}_{2}\mathrm{O}$
