Answer» The given complex isK[Cr(H2O)2(C2O4)2]K[Cr(H2O)2(C2O4)2]. The possible isomers of the given complex are cis and trans form as shown below. Thus, it exhibits geometrical isomerism. The mirror image of cis form of this complex is non-superimposable as shown below. Thus, the cis form exhibits optical isomerism. iiii The given complex is[Co(en)3]Cl3[Co(en)3]Cl3. The mirror image of the given complex is non-super imposable as shown below. Thus, the isomerism it exhibit is optical isomerism. iiiiii The given complex is[Co(NH3)5(NO2)](NO3)3[Co(NH3)5(NO2)](NO3)3. The mirror image of the given complex is non-super imposable as shown below. It can also show linkage isomerism as shown below. It can also show ionization isomerism as shown below. iviv The given complex is[Pt(NH3)(H2O)Cl2][Pt(NH3)(H2O)Cl2]. The possible isomers of the given complex are cis and trans form as shown below. Thus, it exhibits geometrical isomerism.

Answer»

The given complex isK[Cr(H2O)2(C2O4)2]K[Cr(H2O)2(C2O4)2]. The possible isomers of the given complex are cis and trans form as shown below.

Thus, it exhibits geometrical isomerism.

The mirror image of cis form of this complex is non-superimposable as shown below.

Thus, the cis form exhibits optical isomerism.

iiii

The given complex is[Co(en)3]Cl3[Co(en)3]Cl3. The mirror image of the given complex is non-super imposable as shown below.

Thus, the isomerism it exhibit is optical isomerism.

iiiiii

The given complex is[Co(NH3)5(NO2)](NO3)3[Co(NH3)5(NO2)](NO3)3. The mirror image of the given complex is non-super imposable as shown below.

It can also show linkage isomerism as shown below.

It can also show ionization isomerism as shown below.

iviv

The given complex is[Pt(NH3)(H2O)Cl2][Pt(NH3)(H2O)Cl2]. The possible isomers of the given complex are cis and trans form as shown below.

Thus, it exhibits geometrical isomerism.
