Ligand can be defined as anionormolecule that can binds to a centralmetalatom to form acoordination complex.The bonding between metal and ligand generally involves donation of one or more of the ligand'selectron pairs to the central metal atom.
Ligand can affect the stability of complexes in many ways,among which basic character of ligand is also an impotant property.It is found that more basic the ligand,more easily it can donate the electron pairs to the central atom and hence more easily it forms the complexes of greater stability.The ligands that bind H+ firmly can form stable complexes with metal ions and this is the case with F-,so it form complexes more stable than I-.Thats why it is considered as better ligand than I-.
