Chemistry - Coordination Chemistry Question with Solution | TestHub
Find the number of chelating ligand in which atleast one donor atom is oxygen. glycinate ion, diethylene triamine, iminodiacetate ion, 8-hydroxyquinolinate ion, salicylate ion, propylene diamine
Answer:
Solution:
The question asks to identify chelating ligands with at least one oxygen donor atom from the given list.
1. Glycinate ion (H₂N-CH₂-COO⁻): Bidentate, donor atoms are N and O. (Contains O)
2. Diethylene triamine (H₂N-CH₂-CH₂-NH-CH₂-CH₂-NH₂): Tridentate, all donor atoms are N. (No O)
3. Iminodiacetate ion (HN(CH₂COO⁻)₂): Tridentate, donor atoms are N and O. (Contains O)
4. 8-hydroxyquinolinate ion: Bidentate, donor atoms are N and O. (Contains O)
5. Salicylate ion (C₆H₄(OH)COO⁻): Bidentate, donor atoms are O and O. (Contains O)
6. Propylene diamine (H₂N-CH(CH₃)-CH₂-NH₂): Bidentate, all donor atoms are N. (No O)
The ligands with at least one oxygen donor atom are glycinate ion, iminodiacetate ion, 8-hydroxyquinolinate ion, and salicylate ion.
The number of such ligands is 4.
The final answer is
