Which is an example of an **ambidentate** ligand?

  1. Cl⁻
  2. EDTA
  3. Ethylenediamine
  4. $NO_2^-$ (can bind via N or via O)
Show answer and solution

Correct answer: D. $NO_2^-$ (can bind via N or via O)

Ambidentate = two possible donor atoms, but only one binds at a time. $NO_2^-$ binds via N (nitro) or O (nitrito) SCN⁻ binds via S (thiocyanato) or N (isothiocyanato). EDTA and en are polydentate (use multiple donors simultaneously), not ambidentate.
