The octahedral complex exists in two isomeric forms and . Isomer reacts with to give a while precipitate,but does not react with . Isomer gives white precipitate with but does not react with .
Isomers and are
ionization isomers
linkage isomers
co-ordination isomers
solvate isomers
Ionization isomers have the same central metal ion; only the ligands exchange place with anion or neutral ion outside of the co-ordination complex. The sole difference between the two isomers is which ligands are attached to the central metal.
The X isomer of is and the Y isomer is
Their reactions are as follows:
The correct answer is Option A- Ionization isomers.
