JEE Main 2014 — Coordination Compounds Question with Solution

JEE Main 2014 (19 Apr Online)

Question

An octahedral complex with molecular composition M.5NH3.Cl.SO4 has two isomers, A and B. The solution of A gives a white precipitate with AgNO3 solution and the solution of B gives white precipitate with BaCl2 solution .The type of isomerism exhibited by the complex is :

Choose an option

Show full solutionCorrect option: C
Correct answer
CIonisation isomerism

Step-by-step explanation

The central metal atom M is in +3 oxidation state and ionisation isomers due to exchange of ligands outside  & inside the co-ordination sphere are

[M(NH3)5SO4][A]Cl→AgNO3AgCl(s)↓white ppt

[M (N H 3 ) 5 Cl] [B] S O 4 → BaC l 2 BaS O 4 (s) ↓ white  ppt

[A] and [B] are ionisation isomers
