alleryWhich one is an ambidentate ligand?
ANH3 (only N donor)
BH2O (only O donor)
CNO2⁻ (binds via N or O)
DCl⁻ (only Cl donor)
Answer & Solution
Correct answer: C. NO2⁻ (binds via N or O)
NO2⁻ is ambidentate, binding via N (nitro) or O (nitrito).
**Other ambidentate ligands:** SCN⁻ (S or N), CN⁻ (C or N).
NH3, Cl⁻, H2O have single donor atoms.
