This is a question that comes up from time to time for our subject matter specialists. Today, we have the full, extensive explanation as well as the answer for everyone who is interested!
Oxalate is considered to be bidentate due to the presence of two potential bonding sites with the metal M. The chemical formula for oxalate is C2O4, and two of the oxygens will connect to the metal. This makes it bidentate, as opposed to monodentate, which has only a single atom bonding with the metal.
Explain why oxalate is considered to be a bidentate ligand.
Although though it includes four O atoms, each of which has a lone pair of electrons, oxalate ion is considered to be a bidentate ligand. In this particular combination, the iron atom is linked to three different oxalate ions. An octahedral structure is produced when the number of coordination sites is set to 6.
Is carbon dioxide oxide a bidentate ligand?
Because it contains two donor atoms, option (b), also known as (C2O4)2, is the best choice. This is because the ligand (C2O4)2- is able to form a bond to the central atom via both of its donor atoms, making it a bidentate ligand. A bidentate ligand is a ligand that contains two donor groups or atoms, as previously mentioned.
Why isn’t Tetradentate the same as oxalate?
It is not possible for the oxalate anion to be tetradentate. In spite of the fact that there are four oxygen atoms, the ion is flat, and the oxygen atoms are oriented in a variety of ways.
How can one determine whether or not a ligand is bidentate?
With bidentate ligands, there are two lone pairs, and either one of them can form a bond with the metal ion in the middle. The two examples that are most frequently used are 1,2-diaminoethane, which was formerly known as ethylenediamine and is frequently abbreviated as “en,” and the ethanedioate ion.
(L-4) Coordination Compounds: Monodentate, Bidentate, Hexadentate, and Polydentate | JEE NEET
We found 39 questions connected to this topic.
Which one of the following is not a bidentate ligand?
NH3 is the chemical formula for ammonia. Because of what we have seen, we know that the only atom in ammonia that is capable of donating its electron pairs is the N atom. Because of this, we are able to conclude that ammonia is a monodentate ligand and not a bidentate ligand. Take note that a coordination complex is made up of a metal atom at its center and a ligand that is attached to the metal.
Is the formula for h2nch2 a bidentate?
Explanation:The ligand known as glycinato is an asymmetrical bidentate.
Is pyridine a ligand that can bind to both sites?
Picolinic acid is an example of a pyridine derivative that is capable of serving as a bidentate ligand. This type of derivative tends to generate higher coordination number complexes. There are a significant number of complexes that involve pyridines that have been modified in a variety of ways. It is known that these complexes exist in the +1 and + 3 states of Sc and Y.
Is hydrazine a bidentate ligand?
Infrared spectral studies show that hydrazine behaves as a monodentate ligand in its complexes with metal picramates and as a bidentate bridg- ing ligand in all complexes with metal (II) picrates, exl)ept Zn(N2H.).
Is EDTA a ligand that only has one bond?
EDTA is a polydentate ligand that has flexidentate property. In this type of ligand, the core metal atom or ion is coordinated by four oxygen atoms and two nitrogen atoms, which create flexidentate bonds. Hence, EDTA contains a total of six donor atoms in its structure. As a result, EDTA is considered to be a hexadentate ligand.
Is DMG a ligand that can bind to both sites?
Because of this, dimethylglyoximato is considered to be a bidentate ligand because it has two donor sites.
How may oxalates be removed from the body by flushing?
Consuming a lot of water can assist your body in flushing oxalates out of its system. Eating sufficient calcium, which, when digested, binds to oxalates and prevents their absorption. Keeping sodium and sugar intake to a minimum, as high levels of both of these substances have been linked to kidney stones. Obtaining the amounts of vitamin C that are needed for your body; getting too much of it can cause an increase in the creation of oxalic acid in your…
Is it possible for nh2nh2 to behave as ligand?
It is a bidentate ligand, which means that it has two NH donating groups. Cobalt, nickel, and zinc all form complexes, and NH2-NH2 serves as the bridging ligand in those complexes.
Is ACAC a ligand that does not take a side?
(acac-, top) Acetylacetonate is an anionic bidentate ligand, which means that it coordinates metal ions by the use of two oxygen atoms. Acac produces neutral, volatile compounds with divalent metal ions, such as Cu(acac)2 and Mo(acac)2, which are helpful for the chemical vapor deposition (CVD) of metal thin films. Examples of these complexes include Cu(acac)2 and Mo(acac)2.
Is it true that pyrrole is a more effective ligand than pyridine?
On the other hand, pyridine will often donate one electron pair, whereas pyrrole has the potential to donate three electron pairs (to a single metal). Unfortunately, I have not observed a structure in which pyrrole does this. The explanation behind this is quite elementary: Pyrrole is very similar to cyclopentadienyl anion, with the exception that one carbon atom in cyclopentadienyl anion has been substituted with a nitrogen atom.
Is there a ligand for a pi acceptor?
The -acceptor ligands are a subcategory of ligands that are distinguished by the presence of -bonds…. This particular sort of bonding is referred to as -backbonding, and it occurs when the d-orbital of the metal donates its electron density to the vacant -orbital of the ligands.
Is CH3NH2 considered to be a bidentate?
The chemical formula CH3NH2 denotes methylamine as a bidentate ligand.
Is CH3NH2 a monodentate?
… ligands are the donor atoms, molecules, or anions that contribute a pair of electrons to the metal atom or ions in order to create a coordination bond with it… The structure of the Oxalate ion is as follows: Therefore, the methylamine molecule, which has the formula [CH3N2H], has one donor atom, which is nitrogen. As a result, it is what’s known as a monodentate ligand.
Which ligand has the bidentate structure?
The term “bidentate ligand” refers to a ligand that contains two “teeth” or atoms that coordinate directly to the center atom in a complex. Ethylenediamine is a type of ligand that is an example of a bidentate ligand. Only one molecule of ethylenediamine is required to successfully make two bonds to an ion of a metal.
Which ligand is utilized in the process of softening hard water?
Polydentate ligands, such as the well-known hexadentate ligand EDTA, are able to bind the unwanted ions that are found in hard water. These ligands are particularly useful when it comes to binding the magnesium and calcium cations, which, as was noted earlier, are found in extremely high concentrations in hard water solutions.
Which of the following is a field ligand that is the most powerful?
On the other hand, it is common knowledge that ligands whose donor atoms consist of carbon, phosphorus, or sulfur are strong field ligands. According to this series, $CO$ is the most potent ligand among the others since carbon is a donor in this situation, it possesses a double bond $(C = O), and it has a positive charge.
What does it mean to have a diamagnetic complex?
(Fe(CN)6)This may be explained based on the properties of ligands and based on the spectrochemical series. As the CN ligand will have a stronger field than the F ligand, the cyanide complex will have a bigger energy differential in the d orbital. This results in the 4 complex being diamagnetic.
What exactly is the ligand Glycinato?
It is generally agreed that the structure of the glycinato ligand best represents the glycinate in its ligand form… The two residues that have a free lone pair of electrons are the oxygen residue in the COO group and the nitrogen residue in the NH2 group; this is what creates the ligand bidentate.
