Question

$[FeF_{6}]^{3-}$ is paramagnetic due to presence of unpaired electrons in the complex. The five electrons remain unpaired because

A

fluorine is the most electronegative element

B

$F^{-}$ is a weak field ligand hence does not cause pairing of electrons

C

$F^{-}$ is a strong field ligand hence does not cause pairing of electrons

D

pairing does not take place in iron complexes

Answer

$F^{-}$ is a weak field ligand hence does not cause pairing of electrons

Explanation

Solution

$F^{-}$ is a weak field ligand hence it does not cause pairing of electrons. $[FeF_{6}]^{3-}$ :
