(a)

Interpretation Introduction

Interpretation:

The complex, which has three isomers, two of which are enantiomers has to be given from the given set of options.

  $\begin{array}{l}{\text{(1) [Co(NH}}_{\text{3}}{\text{)}}_{\text{3}}{\text{Cl}}_{\text{3}}\text{]}\\ {\text{(2) [Co(en)}}_{\text{2}}{\text{Br}}_{\text{2}}{\text{]}}^{+}\\ {\text{(3) [Cr(H}}_{\text{2}}{\text{O)}}_{\text{2}}{\text{Cl}}_{\text{2}}{\text{Br}}_{\text{2}}{\text{]}}^{-}\\ {\text{(4) [Pt(NH}}_{\text{3}}{\text{)}}_{\text{3}}{\text{SCN]}}^{+}\\ {\text{(5) [Cr(C}}_{\text{2}}{\text{O}}_{\text{4}}{\text{)}}_{\text{3}}{\text{]}}^{3-}\end{array}$

(b)

Interpretation Introduction

Interpretation:

Linkage isomers having complex has to be given from the given set of options.

  $\begin{array}{l}{\text{(1) [Co(NH}}_{\text{3}}{\text{)}}_{\text{3}}{\text{Cl}}_{\text{3}}\text{]}\\ {\text{(2) [Co(en)}}_{\text{2}}{\text{Br}}_{\text{2}}{\text{]}}^{+}\\ {\text{(3) [Cr(H}}_{\text{2}}{\text{O)}}_{\text{2}}{\text{Cl}}_{\text{2}}{\text{Br}}_{\text{2}}{\text{]}}^{-}\\ {\text{(4) [Pt(NH}}_{\text{3}}{\text{)}}_{\text{3}}{\text{SCN]}}^{+}\\ {\text{(5) [Cr(C}}_{\text{2}}{\text{O}}_{\text{4}}{\text{)}}_{\text{3}}{\text{]}}^{3-}\end{array}$

(c)

Interpretation Introduction

Interpretation:

The complex, which does not show optically active isomers, has to be given from the given set of options.

  $\begin{array}{l}{\text{(1) [Co(NH}}_{\text{3}}{\text{)}}_{\text{3}}{\text{Cl}}_{\text{3}}\text{]}\\ {\text{(2) [Co(en)}}_{\text{2}}{\text{Br}}_{\text{2}}{\text{]}}^{+}\\ {\text{(3) [Cr(H}}_{\text{2}}{\text{O)}}_{\text{2}}{\text{Cl}}_{\text{2}}{\text{Br}}_{\text{2}}{\text{]}}^{-}\\ {\text{(4) [Pt(NH}}_{\text{3}}{\text{)}}_{\text{3}}{\text{SCN]}}^{+}\\ {\text{(5) [Cr(C}}_{\text{2}}{\text{O}}_{\text{4}}{\text{)}}_{\text{3}}{\text{]}}^{3-}\end{array}$

(d)

Interpretation Introduction

Interpretation:

The complex that has the greatest number of possible isomers has to be identified and those structures are showed.

  $\begin{array}{l}{\text{(1) [Co(NH}}_{\text{3}}{\text{)}}_{\text{3}}{\text{Cl}}_{\text{3}}\text{]}\\ {\text{(2) [Co(en)}}_{\text{2}}{\text{Br}}_{\text{2}}{\text{]}}^{+}\\ {\text{(3) [Cr(H}}_{\text{2}}{\text{O)}}_{\text{2}}{\text{Cl}}_{\text{2}}{\text{Br}}_{\text{2}}{\text{]}}^{-}\\ {\text{(4) [Pt(NH}}_{\text{3}}{\text{)}}_{\text{3}}{\text{SCN]}}^{+}\\ {\text{(5) [Cr(C}}_{\text{2}}{\text{O}}_{\text{4}}{\text{)}}_{\text{3}}{\text{]}}^{3-}\end{array}$
