Find the number of ligands which can be bonded with metal by nitrogen donor atom, py, , en,
Answer:
Solution:
To find the number of ligands that can bond via a nitrogen donor atom, we examine each species for available lone pairs on nitrogen:
NO₂⁻ (Nitrite): An ambidentate ligand that can bond through either Nitrogen or Oxygen.
py (Pyridine): Bonds through the lone pair on the Nitrogen atom in the aromatic ring.
Gly⁻ (Glycinate): A bidentate ligand that bonds through one Nitrogen and one Oxygen atom.
en (Ethylenediamine): A bidentate ligand that bonds through two Nitrogen donor atoms.
NO₃⁻ and NH₄⁺: Nitrate typically bonds through Oxygen, and the Ammonium ion has no lone pair to donate.
Thus, the total number of ligands that can bond via a nitrogen donor atom is 4.
