Which of the following is correct order of wavelength absorbed by given complexes?
The correct order for the wavelength of absorption in the visible region is. Solution : The absorption of energy or the observation of colour in a complex transition compound depends on the charge of the mtal ion and the nature of the ligands attached.
What is the order of ligands?
Ligands can be arranged in a so-called spectrochemical series in order from strong π acceptors (correlated with low spin, strong field, and large δ values) to strong π donors (correlated with high spin, weak field, and small δ values) as follows: CO, CN− > 1,10-phenanthroline > NO2− > en > NH3 > NCS− > H2O > F− > RCOO− …
Which all are strong ligands?
Strong field ligands contain C, N, and P as donor atoms. e.g. CN– , NCS– , CO, NH3, EDTA, en (ethylenediammine). ii. 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.
Which 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. Note: The strength of any ligand is determined by the amount of crystal field energy (CFT).
Is EDTA a strong field ligand?
EDTA is a moderately strong field, while (en ) is a strong field ligand.
Why is EDTA a strong ligand field?
is EDTA is strong field ligand? Answer: The ligand’s electrons interact with the electrons of the d orbitals, the electrostatic interactions cause the energy levels of the d-orbital to fluctuate depending on the orientation and the nature of the ligands.
Is EDTA a bidentate ligand?
EDTA, a hexadentate ligand, is an example of a polydentate ligand that has six donor atoms with electron pairs that can be used to bond to a central metal atom or ion. Draw metal complexes using the ligands below and metal ions of your choice.
