Question

Match List-I with List-II:

Column 1	Column 2
[Co(NH3)6] [Cr(CN)6]	Linkage isomerism
[Co(NH3)3 (NO2)3]	Solvate isomerism
[Cr(H2O)6]Cl3	Coordination isomerism
cis-[CrCl2(ox)2]3-	Optical isomerism

Answer 1

1. Coordination isomerism: The composition of the coordination complex ion can differ in coordination isomerism, a type of structural isomerism. [Co(NH₃)₆] [Cr(CN)₆] is showing the coordination isomerism.
2. Linkage isomerism: When two or more coordination compounds have at least one ligand with a different donor atom, this is known as a linkage isomer. [Co(NH₃)₃ (NO₂)₃] is showing the linkage isomerism as nitrogen and oxygen both can attach to the cobalt.
3. Solvate isomerism: When water is used as a solvent, the term "hydrate isomerism" is used instead of "solvate isomerism." Whether a solvent molecule is directly linked to the metal ion or is only present as free solvent molecules in the crystal lattice determines how different solvent isomers are. [Cr(H₂O)₆]Cl₃ will show the solvate isomerism.
4. Optical isomerism: Two compounds that have distinct spatial arrangements of the atoms, the same number and types of atoms, bonds (i.e., the connection between atoms is the same), and optical isomers are non-superimposable mirror images of one another. cis-[CrCl₂(ox)₂]^3- will show the optical isomerism.

Final Answer: Hence, the correct match is given as-

List-1	List-2
[Co(NH3)6] [Cr(CN)6]	Coordination isomerism
[Co(NH3)3 (NO2)3]	Linkage isomerism
[Cr(H2O)6]Cl3	Solvate isomerism
cis-[CrCl2(ox)2]3-	Optical isomerism
