IUPAC Name of EDTA: 2,2′,2″,2′″-(ethane-1,2-diyldinitrilo-)κ^2N

In summary, according to IUPAC Nomenclature of Inorganic Chemistry, the correct name for edta chelate is 2,2′,2″,2′″-(ethane-1,2-diyldinitrilo-κ^2N)tetraacetato-κ^4O. While edta coordinates through Nitrogen and Oxygen atoms, there is no metal-carbon bond. The "yl" suffix in the name does not indicate a metal-carbon bond, as it is commonly used to indicate substitution for a hydrogen. However, in organometallic compounds, the "yl" or "ido" suffixes are used to indicate a metal-carbon bond, as seen in the example

As per IUPAC Nomenclature of Inorganic Chemistry, the correct name of the edta chelate is $$\text{2,2′,2″,2′″-(ethane-1,2-diyldinitrilo-} κ^2 \text{N)tetraacetato-}κ^4O $$ As far as I know, edta coordinates through Nitrogen and Oxygen atoms, and there is no metal-carbon bond.

On the other hand, the "yl" in the name indicates a metal-carbon bond, because the "yl" or "ido" suffixes are for organometallic compounds. For example, the complex ##[Ti(CH_2 CH_2 CH_3) Cl_3] ## compund is named ##\text{trichlorido(propan-1-yl)titanium}## as per the organometallic nomenclature system.

Then why has the "yl" suffix been used in edta?

Related to IUPAC Name of EDTA: 2,2′,2″,2′″-(ethane-1,2-diyldinitrilo-)κ^2N

1. What does "IUPAC" stand for?

IUPAC stands for International Union of Pure and Applied Chemistry. It is the organization responsible for standardizing the names and terminology used in chemistry.

2. What is the full name of EDTA?

The full name of EDTA is ethylenediaminetetraacetic acid.

3. What does the number "2" represent in the IUPAC name of EDTA?

The number "2" represents the number of carbon atoms in the ethane-1,2-diyldinitrilo chain in EDTA.

4. What do the symbols "κ^2N" mean in the IUPAC name of EDTA?

The symbols "κ^2N" indicate the coordination of the nitrogen atoms in EDTA, meaning they are bonded to the central metal ion in a certain way.

5. Why is it important to use the IUPAC name when referring to EDTA?

Using the IUPAC name ensures that there is one universal name for a compound, avoiding confusion or misinterpretation. It also follows a set of rules for naming compounds, making it easier to understand the chemical structure and properties of EDTA.
