Which ligand is capable of forming low spin and high spin complexes?
sp3d2The complexes formed by hybridization are low-spinning complex or high-spinning complex.
Which ligand is capable of forming low spin?
Strong-field ligands, like CN- and NO2-, increase Δ which results in low spin. While weak-field ligands, like I- and Cl-, decrease the Δ which results in high spin.
What are high spin and low spin complexes explain with examples?
The terms high spin and low spin are related to coordination complexes. These are called spin states of complexes. We can determine these states using crystal field theory and ligand field theory. Generally, octahedral complexes and tetrahedral complexes are high spin, while square planar complexes are low spin.
Which of the following ligands is most likely to form high spin complexes in octahedral field?
Which of the following ligands is most likely to form high spin complexes in octahedral fields? Explanation: Cl- is the weakest field ligand in the given options. The splitting field Δo is small and the energy separation between the eg and t2g orbitals are narrower.
Which of the following is Hexadentate ligand?
EDTA
EDTA is a hexadentate ligand.
For which transition metal ions are low spin complexes possible?
Due to strong ligand pairing occurs and all have vacant ‘d’ orbital, thus, it can from low spin complex. It is present in low oxidation state, so, it forms low spin complex.
Which is a high spin complex?
High spin-complex- is the complex which possesses a greater number of unpaired electrons in the d-orbitals of the central metal atom and it will be paramagnetic in nature. As the ligand is a weak ligand the splitting of d-orbitals will be less .
Which of the following is are high spin complex?
[Fe(CN)6]−3 is low spin complex but [Fe(H2O)6]+3 is high spin complex.
Is fe3 high-spin low spin?
Octahedral low-spin: 1 unpaired electron, paramagnetic, substitutionally inert. Includes Fe3+. Example: [Fe(CN)6]3−. Octahedral high-spin: 4 unpaired electrons, paramagnetic, substitutionally labile.
What are strong ligands and weak ligands?
Strong field ligands: Those ligands which cause larger splitting of d orbitals and favour pairing of electrons are called strong field ligands. Strong field ligands contain C, N, and P as donor atoms. Weak field ligands contain halogen, O, and S as donor atoms. e.g. F– , Cl– , Br– , I–, SCN–, C O C 2 O 4 2 – .
Is fe3 high spin low spin?
Which of the following is low spin complex?
A low spin (or spin-paired) complex, such as [Co(NH3)6]3+ is one in which the electrons are paired up to give a maximum number of doubly occupied d orbitals and a minimum number of unpaired electrons. Usually inner orbital complexes (d2sp3) are low-spin (or spin paired) complexes.
What is an example of a low spin d6 complex?
The usual Hund’s rule and Aufbau Principle apply. Examples of low-spin d6 complexes are [Cr(CN)6]3− and Cr(CO)6, and examples of high-spin d6 complexes are [CrCl6]3− and Cr(H2O)6. I assume you know the basic facets of crystal field theory:
What is high spin and low spin in chemistry?
A complex can be classified as high spin or low spin. When talking about all the molecular geometries, we compare the crystal field splitting energy (Δ) and the pairing energy (P). Normally, these two quantities determine whether a certain field is low spin or high spin.
Can some weak ligands act as strong field ligands?
Some times there are exceptional case when some weak field ligands acts as strong field ligand for example: [PtCl4]2-, CoF6 Here these ligands act as strong field ligands. Thanks for A2A!!!
What is a high spin complex?
High spin complexes are ones with unpaired elctrons and hence paramagnetic.These compunds have higher total spin number and hence are called high spin complexes.
