MHT CET 2024 Chemistry question

What type of isomerism is exhibited by and

(1)Coordinate
(2)SolvateCorrect
(3)Ionization
(4)Linkage

Answer: (2)

Solution

Both complexes have the formula but differ in the number of water molecules present as ligands inside the coordination sphere (six in the first, five in the second) and as water of crystallisation outside it. This is solvate (hydrate) isomerism. Hence (2). Ionisation
