ChemistrySingle correct+4 / -1Question 43 of 90

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

Linkage isomerism

Ionisation isomerism

Coordinate isomerism

Geometrical isomerism

Answer and worked solution

Official answer: B

A: $\ce{[M(NH3)5SO4]Cl}$ , with $\ce{Cl-}$ outside, gives AgCl.
B: $\ce{[M(NH3)5Cl]SO4}$ , with sulphate outside, gives $\ce{BaSO4}$ .

The isomers differ in which ion is outside the coordination sphere: ionisation isomerism.
