In today's NEET Chemistry cheat code session we will learn Trick to Identify SFL (Strong field ligand ) & WFL (Weak field ligand) from coordination compounds ...

Strong and weak field ligands. The spectrochemical series ranks ligands according the energy difference ΔO between the t 2g and e g orbitals in their octahedral complexes.

2015年9月2日 · When a metal ion having higher charge is interacting with ligand NH3 it acts as a SFL. When the metal ion has lower charge it acts as WFL. EG: $\ce{Co^2+}$ and $\ce{Co^3+}$ In $\ce{Co^2+}$ $\ce{NH3}$ acts as WFL.

2023年11月15日 · My teacher taught me that VBT is based on the experimental values of magnetic moment, whereas CFT focuses on orbitals splitting in the presence of weak and strong field ligands (WFL and SFL, respectively). Can we explain VBT configuration on …

Weak field ligands: H 2 O, F −, Cl −, OH −. Strong field ligands: CO, CN −, NH 3, PPh 3. Ligands arranged on the left end of this spectrochemical series are generally regarded as weaker ligands and cannot cause forcible pairing of electrons within the 3d level, and thus form outer orbital octahedral complexes that are high spin.

Spectrochemical series gives the arrangement of ligands in the increasing order of crystal field splitting. Weak field ligands cause less crystal field splitting. They form high spin complexes. Examples include chloride ions, fluoride ions etc. Strong field ligands cause greater crystal field splitting. They form low spin complexes.

Explain the difference between a weak field ligand and a strong field ligand. A spectrochemical series is the arrangement of common ligands in the increasing order of their crystal-field splitting energy (CFSE) values. The ligands present on the R.H.S of the series are strong field ligands while that on the L.H.S are weak field ligands.

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 -. Theories of Bonding in Complexes.

2022年5月6日 · For metals with +2 oxidation state(in3d series) ligands from I- to EN are considered WFL and all others are SFL For metals with +3 state in 3d series ligands from I- to H2O are considered WFL and rest all SFL
