An octahedral complex with the molecular composition `M.5NH_(3).Cl.SO_(4)` has two isomers A and B. The solution of A gives a white precipitate with `AgNO_(3)` solution and the solution of B gives white precipitate with `BaCl_(2)` solution. The type of isomerism exhibited by the complex is

A

Linkage isomerism

B

lonization isomerism

C

Coordinate isomerisi

D

Geometrical isomerism

Text Solution

Verified by Experts

The correct Answer is:
B
A and B are two isomers of M. `5NH_3 . Cl . SO_4`
`underset((A))(M. 5NH_3 . Cl. SO_4) overset(AgNO_2)to` White ppt.
`underset((B)) (M . 5 NH_3 . Cl. SO_4) overset(BaCl_2)to` White ppt.
`Ag^(+)` ion gives white precipitate with both `Cl^(-) and SO_4^(2-)` but `Ba^(2+)` ion gives white prccipitate only with `SO_4^(2-)`. Hence in complex `B SO_4^(2-)` must present outside the complex sphere.
Structure of `B = [M (NH_3)_5Cl]SO_4`
Structure of `A = [M (NH_3)_5SO_4]Cl`
A and B should be ionization isomer
