Is ethylenediamine a strong or weak field ligand?

Is ethylenediamine a strong or weak field ligand?

Next we have ethylenediamine. It lies towards the right in the series and also uses its nitrogen atom to bind with the metal atom therefore ‘en’ is a strong field ligand.

Is ethylenediamine a good ligand?

Ethylenediamine is a well-known bidentate chelating ligand for coordination compounds, with the two nitrogen atoms donating their lone pairs of electrons when ethylenediamine acts as a ligand.

Is en a strong ligand or weak ligand?

– ${F^ – },{I^ – },C{l^ – },{H_2}O$ are weak ligands, others are strong ligands. This statement is false as en is also a weak ligand. en stands for ethylene diamine ligand. Therefore, enter 0.

Is ethylenediamine high spin or low spin?

[Fe(H2O)6]2+ and [Fe(en)3]2+ (en = ethylenediamine) are typical examples of high-spin complexes, while [Fe(CN)6]4− and [Fe(bpy)3]2+ (bpy = 2,2′-bipyridine) contain strong-field ligands and are low-spin.

Why is Bipyridine a strong field ligand?

In fact bipyridine forms a chelate with a metal ion and thus the complex formed is more stable. Therefore, bipyridine is a stronger ligand than pyridine because it is a bidentate ligand.

Why is PPh3 a strong field ligand?

According to crystal field theory and spectrochemical series, PPh3 is a strong field ligand because it will produce strong splitting. Answer: According to Crystal Field Theory and Spectrochemical series, PPh3 is a Strong field ligand because of it will produce strong splitting (large Δ) .

Is ethylenediamine a strong base?

Ethylenediamine (EDA) is a colorless, alkaline liquid with an ammonia-like odor. It is a strong base that’s soluble in water, alcohol, ether, and insoluble in benzene.

Is En weak field ligand?

Weak field ligands: Those ligands which cause lower splitting of d orbitals i.e., ∆° parameter is smaller compared to the energy required for the pairing of electrons are called weak field ligands. 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 ACAC a weak field ligand?

An easy way to identify this: The ligands in which the donor atom is Nitrogen and carbon is a strong field ligand and the ligand in which the donor atom is a halogen or oxygen is a weak field ligand. So in acac the donating atoms are Oxygen making it a weak field whereas in NH3 the donating is N making it strong field.

What is the effect of a stronger ligand?

Strong-field ligands repel the metal’s electrons very effectively, producing large splits. Weak-field ligands only partly repel the electrons, producing smaller splits. While the size is partly ligand-dependent, both the size and number of energy splits is primarily affected by the geometry of the complex.

Which of the following is the strongest ligand?

According to this series $CO$ is the strongest ligand among the following because carbon is donor in this, it has double bond $(C = O)$ and is positively charged.
