  • Match the complex species given in Column I with the possible isomerism given in Column II and assign the correct code:

In the following question match the items given in Columns I and II.

Match the complex species given in Column I with the possible isomerism given in Column II and assign the correct code :

Column I (Complex species) Column II (Isomerism)
A. [Co (NH_{3})_{4}Cl_{2}]^{+} 1. Optical
B. cis-[Co (en)_{2}Cl_{2}]^{+} 2. Ionisation
C. [Co (NH_{3})_{5}(NO_{2})]Cl_{2} 3. Coordination
D. [Co (NH_{3})_{6}]\left [ Cr(CN)_{6} \right ] 4. Geometrical
  5. Linkage

(i) A (1) B (2) C (4) D (5)

(ii) A (4) B (3) C (2) D (1)

(iii) A (4) B (1) C (5) D (3)

(iv) A (4) B (1) C (2) D (3)

Option (iv) is the correct answer.

Explanation : The types of ligands, arrangement of ligands and the geometry of coordination decide the isomerism in coordination compounds.

(a) [Co (NH_{3})_{4}Cl_{2}]^{+} shows geometrical isomerism due to presence of two types of ligand whoes [Co (NH_{3})_{4}Cl_{2}]^{+} arrangement around central metal ion

(b) cis-[Co (en)_{2}Cl_{2}]^{+} shows optical isomer due to its non - superimposable mirror image relationship.

(c) [Co (NH_{3})_{5}(NO_{2})]Cl_{2}  shows ionization isomer due to its interchanging ligand from outside the ionization sphere.

(d) [Co (NH_{3})_{6}]\left [ Cr(CN)_{6} \right ]  shows coordination isomerdue to interchanging of ligand in between two metal ions from one coordination sphere to another coordination sphere.

Hence, correct choice is (iv)
