Chelates Ligands in Coordination compound || Chelate effect || Multidentate ligands

A chelate is a compound that has two or more coordinate or dative bonds between a ligand (usually organic) and a central metal atom.Chelating ligands, also known as multidentate ligands, are compounds that may make several bonds to a single metal ion. Here, we learn about the chelate, chelation and chelate effects. Types of Ligands One or more donor sites can be detected in a ligand. Ligands can be one of the following categories, depending on the number of donor sites: 1. Monodentate or unidentate ligands 2. Bidentate ligands 3. Polydentate ligands A ligand is said to be monodentate if it can only establish one coordinate covalent bond per molecule. If there are two donor sites, the ligand is a ‘bidentate ligand’. The denticity of ligands describes this classification. Because the ligand in a chelate is linked to the central metal atom via two or more donor sites, the ligand is either bidentate or polydentate. The ligand of a chelate is usually cyclic or ring in structure. Chelating agents are another name for these ligands. Chelating Ligands Meaning Chelating ligands, also known as ‘multidentate ligands’, are compounds that may make several bonds to a single metal ion. Ethylenediamine and oxalate are two simple (and common) examples. Chelate A chelate is a molecule that consists of a central metal atom that is linked to a ligand that has at least two or more donor sites. As a result, the chelate is the entire complex that includes the core metal atom and the ligand. This complex is also known as a coordination compound or coordination complex. A chelate has only one ligand, but certain coordination complexes attach two or more ligands to the central metal atom. Chelate effect The metal-ligand relationship is more stable when a ligand forms a ring with a metal ion. In other words, complexes containing chelate rings are more stable than complexes lacking rings, and this is known as the chelate effect. Ethylenediamine is a well-known chelating ligand (NH₂ CH₂ CH₂ NH₂). Using the two nitrogen atoms present can establish a connection with a metal ion. Distinction Between a Ligand and a Chelate The terms ligand and chelate are very closely related. The main difference between ligands and chelates is that ligands are chemical substances that donate or share electrons with a central atom via coordination bonds. In contrast, chelates are compounds with a central atom connected to surrounding ligands. Conclusion It is reasonable to conclude that ligands are the fundamental building blocks of coordination molecules. In coordination, a chemical ligand is a molecule or ions that connect with the central metal atom and produce a coordination complex. It functions as an electron-pair donor, whereas the centre atom functions as an electron pair acceptor. The terms ligand and chelate are often used in coordination chemistry. The main difference between ligands and chelates is that ligands donate or share electrons with a central atom via coordination bonds. In contrast, chelates are compounds with a central atom bonded to surrounding ligands. The creation of a cyclic configuration around the core metal atom is caused by di- and polydentate ligands. Such a cyclic metal complex is known as a chelate, and the ligands that produce chelates are known as chelating ligands, and the process is known as chelation. When a ligand forms a ring with a metal ion, the metal-ligand relationship is shown to be more stable. In other words, complexes containing chelate rings are more stable than complexes lacking rings, and this is known as the chelate effect. ligands #shorts #coordination compounds #ambidentate ligand #chemistry Chelates Ligands in Coordination compound A to Z || Chelate effect || Multidentate ligands #BSc #NEET #JEE Key words: #chemistry #coordination #coordinationcompounds #dentist #inorganicchemistry #12th #12thclass #12thchemistry #ligands #chemistryeducation #chemistrynotes @BipChemTech You can see more about this topic through Google search.
