Which of the following is a Chelating ligand? |
thiocyanate cyanide Oxalate Ammonia |
Oxalate |
The chelating ligand among the options is (3) oxalate. A chelating ligand is a ligand that can donate more than one pair of electrons to a metal atom. This results in the formation of a chelate complex, which is a complex in which the ligand forms a ring around the metal atom. Thiocyanate, cyanide, and ammonia are all monodentate ligands, which means that they can only donate one pair of electrons to a metal atom. Therefore, they cannot form chelate complexes. Oxalate is a bidentate ligand, which means that it can donate two pairs of electrons to a metal atom. This allows it to form a chelate complex with the metal atom. |
