Which of the following sets of ligands does NOT contain ambident ligand in it?
Options
- AOxalate ion, NO ₂^- , NCS ^-
- BC ₂ O ₄²⁻ , Ethylene diamine, H ₂ O
- CNO ₂^- , C ₂ O ₄²⁻ , EDTA ⁴⁻
- DEDTA ⁴⁻ , NCS ^- , Oxalate ion
Correct answer
B. C ₂ O ₄²⁻ , Ethylene diamine, H ₂ O
Step-by-step solution
An ambidentate ligand is a ligand that has more than one type of donor atom and can bind to the central metal ion through any of these different donor atoms. Examples of ambidentate ligands include NO ₂^- (which can bind through N or O) and NCS ^- (which can bind through N or S). Checking the given options: Option 1 contains NO ₂^- and NCS ^- , both of which are ambidentate ligands. Option 2 contains C ₂ O ₄²⁻ (binds only through O), ethylene diamine (binds only through N), and H ₂ O (binds only through O). None of
