Question

Compounds which have the same molecular formula but differ in their properties due to differences in structure or orientation in 3D are known as isomers.

So for a complex $[C o (e n)_{2} (B r) (N O_{2})] Cl \cdot H_{2} O$ .

$X =$ Number of types of isomerism that can be shown by this complex among the following: Linkage, Coordination, Ionization, Geometrical, and Hydrate.

$Y =$ Maximum possible stereoisomers for the given complex.

Find the sum of $X + Y$ .

Isomerism types ( X = 4 ): It shows Linkage (due to ambidentate NO₂⁻), Ionization (exchanging inner ligands with Cl⁻), Hydrate (exchanging inner ligands with H₂O), and Geometrical isomerism. Coordination isomerism is absent. Stereoisomers ( Y = 3 ): The octahedral complex [ M ( AA ) 2 ​ b c ] type forms one optically inactive trans-isomer and a pair of optically active cis-enantiomers (d and l forms). Final Sum: X + Y = 4 + 3 = 7 .
