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 correctly matched against indicated isomerism ?
Options:(select one or more)
Answer:
Solution:
1. [Co(NH₃)₄(H₂O)Cl]Br₂ shows ionisation isomerism due to exchange of Cl⁻ and Br⁻ → correct
2. [Rh(PPh₃)₂(CO)(NCS)₂] shows linkage isomeris via ambidentate NCS⁻ ligand → correct
3. [Pt(NH₃)₄][PtCl₄] shows coordination isomerism due to ligand exchange between complex ions → correct
4. [Zn(gly)₂] does not show geometrical isomerism → incorrect
Final Answer: A, B, C
