Topic Question Set

Q 1 :    

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:                                [2024]

  • A-II, B-III, C-IV, D-I

     

  • A-I, B-III, C-IV, D-II

     

  • A-I, B-IV, C-III, D-II

     

  • A-II, B-IV, C-III, D-I

     

(1)

A–(II), B–(III), C–(IV), D–(I)

 

Q 2 :    

Type of isomerism exhibited by compounds [Cr(H2O)6]Cl3, [Cr(H2O)5Cl]Cl2.H2O, [Cr(H2O)4Cl2]Cl.2H2O and the value of coordination number (CN) of central metal ion in all these compounds, respectively is            [2023]

  • geometrical isomerism, CN = 2

     

  • optical isomerism, CN = 4

     

  • ionisation isomerism, CN = 4

     

  • solvate isomerism, CN = 6

     

(4)

The isomers that exhibit solvate isomerism have the same composition but differ with respect to the number of solvent ligand molecules as well as the counter ion in the crystal lattice.

Given complex compounds exhibit solvate isomerism and the coordination number of central metal ion is 6.

 

Q 3 :    

The type of isomerism shown by the complex [CoCl2(en)2] is             [2018]

  • geometrical isomerism

     

  • coordination isomerism

     

  • ionization isomerism

     

  • linkage isomerism

     

(1)

[CoCl2(en)2], exhibits geometrical isomerism, as the coordination number of Co is 6 and this compound has octahedral geometry.
