Explain the following:Bidentate ligand with an example.

A bidentate ligand is a type of ligand in coordination chemistry that has two donor atoms capable of forming coordination bonds with a central metal ion. These ligands are also sometimes referred to as "chelating ligands" because they can form a chelate complex with the metal ion. The term "bidentate" is derived from the Latin words "bi" (meaning two) and "dentatus" (meaning teeth), indicating that these ligands can "bite" the metal ion at two different points.

Bidentate ligands are important in coordination chemistry because they can form more stable and kinetically inert complexes with metal ions compared to monodentate ligands (ligands with only one donor atom). The chelate effect, which is the increased stability of chelate complexes compared to non-chelate complexes, is a well-known phenomenon associated with bidentate ligands.
