An octahedral complex having molecular composition Co. 5 NH 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,
Options
- ACo-ordinate isomerism
- BLinkage isomerism
- CIonisation isomerism
- DGeometrical isomerism
Correct answer
C. Ionisation isomerism
Step-by-step solution
(A) complex is [ Co ( NH ₃ )₅ ( SO ₄ ) ] Cl (B) complex is [ Co ( NH ₃ )₅ Cl ] SO ₄ Both ( A ) and ( B ) are Ionisation isomers.
