An octahedral complex having molecular composition Co.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

Question

An octahedral complex having molecular composition Co.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,

(A) Linkage isomerism
(B) Ionisation isomerism
(C) Co-ordinate isomerism
(D) Geometrical isomerism

Prashant Kotian · Accepted Answer

Correct answer: B. ution 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, (1) Linkage isomerism (2) Ionisation isomerism (3) Co-ordinate isomerism (4) Geometrical isomerism Ans. (2) Sol. (A) Complex is [Co(NH3)5(SO4)]Cl (B) Complex is [Co(NH3)5 Cl]SO4 Both (A) and (B) are ionisation isomers.
