WebMay 31, 2015 · This is what my textbook says: All polydentate ligands are the example of chelating ligands. However, it must be noted that $\ce{NH2NH2}$ and $\ce{N(CH2CH2)N}$ cannot act as chelating ligands due to the formation of a three membered ring and locked structure respectively.

The words chelator and chelating ligand are also …
What Is a Chelate in Chemistry? - ThoughtCo
WebMar 11, 2024 · A good example is ethylenediamine (NH 2 CH 2 CH 2 NH 2), which can bond to a metal ion through each of the two nitrogens. Chelating ligands can have several points of attachment. Chelating … WebA chelate is an organic compound which combines with and protects certain metallic cations such as Fe, Mn, Cu and Zn etc. The cation-chelate combinations are complex ring structures and the metals so bound essentially lose their usual ionic characteristics (Fig. 20.19). Chelates are sometimes called siderophores. lawrence susskind
Are all complexes with a polydentate ligand examples of chelation?
WebChelation. Chelation is the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central atom. Usually these ligands are organic compounds and are called chelants, chelators, chelating agents, or sequestering agents; the resulting complexes are called chelate compounds. WebApr 21, 2015 · Chelate is any of a class of coordination or complex compounds consisting of a central metal atom attached to a large molecule, called a ligand, in a cyclic or ring … WebHere is a basic example of the role chelates play in making nutrients available to plants: Many trace elements in their basic form(s) are unavailable to plants.
