Co-Ordination Compounds Question 244
Question: An octahedral complex with molecular composition M.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:
A) Linkage isomerism
B) lonisation isomerism
C) Coordinate isomerism
D) Geometrical isomerism
Show Answer
Answer:
Correct Answer: B
Solution:
The two possible isomers for the given octahedral complex are $ [M{{(NH_3)}_5}SO_4]Cl $ and $ [M{{(NH_3)}_5}Cl],SO_4 $ .
They respectively give chloride ion (indicated by precipitation with $ BaCl_2 $ ) and $ SO_4 $ ion (indicated by precipitation with $ AgNO_3 $ ).
Hence the type of isomerism exhibited by the complex is ionization isomerism.
