Question

# Taking an example of an ambidentate ligand, explain why it is called an ambidentate ligand.

Some ambidentate ligands are $CN^{ - },\quad N{ O }_{ 2 }^{ - },\quad CN{ S }^{ - }$.
Let us consider $CN^{ - }$ ion. Cyanide ion acts as a ligand because of the presence of lone pairs of electrons on both nitrogen and carbon atoms.
