As we have learned

Types of Ligands on the basis of Connectivity -

(i) Unidentate - ligand is bound to metal ion through a single donor atom.

eg: Cl^{-}, H_{2}O and NH_{3}

(ii) Bidentate : when ligand can bind through two donor atoms

eg: CH_{2}NH_{2}-CH_{2}NH_{2}

(iii) Polydentate - when ligand bind to two or more donor atoms

(iv) Hexadentate - type of polydentate having six donor atoms

(v) Ambidentate- which can ligate through two different atoms at a time

eg. M\leftarrow SCN & M\leftarrow NCS

- wherein

All ambidentate ligands are monodentate but all monodentate ligands are not ambidentate

   

 

 

As it makes use of its two atoms to form two co-ordinate covalent bonds with the central metal ion.

 

 

 


Option 1)

  Acetate

Option 2)

Oxalate

Option 3)

  Thiocyanate

Option 4)

  EDTA
