What is meant by hexadentate ligand?
A ligand that has 6 lone pairs of electrons – all of which can form co-ordinate bonds with the same metal Ion.
Why is EDTA a hexadentate ligand?
Hexadentate ligand is one in which there are six donor atoms . As we can see from the structure that it has six donor atoms , that is , two nitrogen and four oxygen atoms ( of the carboxylic acid groups ) capable of bonding to the metal atom . Hence it is a hexadentate ligand .
Which is example of hexadentate ligand?
Ethylene diamine tetra acetate ion [EDTA] is an example of hexadentate ligand.
What is hexadentate ligand class 12?
The ligands which bind with metal through six atoms are known as a hexadentate ligand. Ethylenediamine tetra acetate ion is a hexadentate ligand as it has six donor sites, two nitrogen and four oxygen atoms. Therefore option (D) Ethylene diamine tetra acetate ion (EDTA) is correct.
What is Flexidentate ligand example?
These ligands are called flexidentate ligands. For example, in complexes [Cr(OH)(HEDTA)] 2– and [CoBr(HEDTA)] 2–, EDTA acts as pentadentate ligand and in complex [Pd(H 2EDTA)] 0, it acts as tetradentate ligand and in complexes [Ca(EDTA)] 2– or [Mg(EDTA)] 2– it acts as hexadentate ligand.
Is EDTA strong ligand?
en. CO.
Is a hexadentate ligand?
A hexadentate ligand in coordination chemistry is a ligand that combines with a central metal atom with six bonds. One example of a hexadentate ligand that can form complexes with soft metal ions is TPEN. A commercially important hexadentate ligand is EDTA.
Which is an example of a hexadentate ligand?
A hexadentate ligand in coordination chemistry is a ligand that combines with a central metal atom with six bonds. One example of a hexadentate ligand that can form complexes with soft metal ions is TPEN. A commercially important hexadentate ligand is EDTA .
What is the meaning of the word ligand?
A ligand is an ion or molecule, which donates a pair of electrons to the central metal atom or ion to form a coordination complex. The word ligand is from Latin, which means “tie or bind”.
Which is the best description of a bidentate ligand?
Ethylenediamine (en) is a bidentate ligand that forms a five-membered ring in coordinating to a metal ion M Polydentate Ligands Polydentate ligands range in the number of atoms used to bond to a central metal atom or ion.
Why are monodentate ligands called one toothed ligands?
Classification of ligands is on the basis of the number of binding sites with the central metal atom, charge and size. Monodentate ligands are also called “one-toothed“ because they bite the metal atom only in one place.
