Chemistry - Coordination Chemistry Question with Solution | TestHub
Isomers in coordination chemistry include many types. In structural isomers hydrate or solvent isomers, ionisation isomers and coordination isomers have same overall formula but have different ligands attached to the central atom or ion.
The terms linkage isomerism or ambidentate isomerism are used for cases of bonding through different atoms of the same ligand.
Stereoisomers have the same ligands, but differ in the geometric arrangement of the ligands.
Which of the following is NOT correctly matched against indicated isomerism ?
Options:
Answer:
Solution:
Question Explanation:
Identify incorrect match of complex with type of isomerism.
Concept:
Types of isomerism in coordination compounds.
Solution:
Option 1 shows ionisation isomerism correctly, as exchange of Cl⁻ and Br⁻ can lead to different ions in solution.
Option 2 is correct since NCS⁻ can bind via N or S, showing linkage isomerism.
Option 3 is correct as it involves exchange of ligands between two metal centres, showing coordination isomerism.
Option 4 is incorrect: [Zn(gly)2 ] is tetrahedral and tetrahedral complexes do not show geometrical isomerism because their ligands are symmetrically arranged and cannot form cis-trans isomers.
