Which type of ligand is EDTA?
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 are the classification of ligands?
Ligands can be classified on the basis of many things. The most common classification of ligands is on the basis of their binding sites with the central metal atom or ion. On the basis of the number of sites, ligands can be classified as monodentate, bidentate, polydentate etc. ligands.
What are ligands and how are they classified?
The molecules or ions which are co-ordinated to the metal atom or ion in a coordination compound are called ligands or donor groups. Based on the number of donor atoms in ligand (denticity), the ligands are classified into the following. Type of ligand. Number of donor atoms.
Is EDTA a neutral ligand?
A ligand can be an anion or a neutral molecule that donates an electron pair to the complex (NH3, H2O, Cl-). The number of ligands that attach to a metal depends on whether the ligand is monodentate or polydentate….Rule 2: Neutral Ligands.
| Short name | Extended name |

Why EDTA is a hexadentate ligand?
$EDTA$ is a hexadentate ligand and hence it coordinates through two nitrogen atoms and four oxygen atoms with the metal ion and forms stable complexes . Since , the metal ions ( $C{a^{2 + }},M{g^{2 + }}$ ) form stable complexes with $EDTA$ , it is used to remove the hardness of water .
Is no Ambidentate ligand?
Another example of an ambidentate ligand is NO2-. This ion can bind to a central atom through either the nitrogen or one of the oxygen atoms, but again, not at the same time. For example, then SCN- binds through the lone pair of electrons on the S atom, the complexes are called thiocyanate.
Is Co a neutral ligand?
Examples of common ligands are the neutral molecules water (H2O), ammonia (NH3), and carbon monoxide (CO) and the anions cyanide (CN-), chloride (Cl-), and hydroxide (OH-).
How are ligands classified according to their charge?
Ligands are classified based on the number of lone pair electrons available for the central metal atom, size and charge like anionic, cationic, neutral, monodentate, bidentate, polydentate ligands. 1.
Which is a ligand in a coordination complex?
In coordination chemistry, a ligand is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex. 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.
Which is an example of an organic ligand?
Organic ligands – A organic derivatives of above mentioned inorganic ligands and they forms a strong bridge between metal centers. Note: Hapticity is the number of atoms of the ligand, which are bound to the central metal atom.
Which is the best description of a monodentate ligand?
Ligands can be classified as monodentate or polydentate ligands (viz. Bidentate, tridentate,), depending on the number of ligands donor atoms that attach to the metal ion or atom. (1) Monodentate Ligands: A ligand which shares electron pair of a single donor atom with a metal atom or ion is called a monodentate ligand.
