Question

Match List I with List II
List-I
(Complex)| List-II
(Type of isomerism)
---|---
(A)| [Co(NH3)5(NO2)]Cl2| (I)| Solvate isomerism
(B)| [Co(NH3)5(SO4)]Br| (II)| Linkage isomerism
(C)| [Co(NH3)6] [Cr(CN)6]| (III)| Ionization isomerism
(D)| [Co(H2O)6]Cl3| (IV)| Coordination isomerism

Choose the correct answer from the options given below:

• A. A-II, B-III, C-IV, D-I
• B. A-I, B-III, C-IV, D-II
• C. A-I, B-IV, C-III, D-II
• D. A-II, B-IV, C-III, D-I

Answer 1

Answer: (A)

A-II, B-III, C-IV, D-I

Answer 2

- Complex A exhibits ionization isomerism because $NO_2^-$ can ionize.
- Complex B shows solvate isomerism due to $SO_4^{2-}$ exchange with water molecules.
- Complex C shows coordination isomerism between the two metal centers.
- Complex D shows linkage isomerism because $Cl^-$ can bind in multiple ways.
