SECTION - C
(a) On the basis of crystal field theory write the electronic configuration for [Atomic number:
Solution: 👈: Video Solution
It is a magnitude difference in energy between the two sets of d-orbital i.e. t 2 g d 5 Δ 0 < P
thent 2 g 3 e g 2
Because it follows weak field ligand phenomina when weak field ligands are present in a structure pairing of electrons do not take place.
∵ so[ F e ( C N ) 6 ] 3 − = C N
F e = 26 , [ A r ] 3 d 6 4 s 2
F e 3 + = 3 d 5
If strong field ligand is available then
Δ 0 > P = t 2 g 5 e g
In[ F e ( F 6 ) ] 3 − , F e = [ A r ] 3 d 6 4 s 2
F e 3 + = 3 d 5
Δ 0 < P
∵ 3 d
then
Because it follows weak field ligand phenomina when weak field ligands are present in a structure pairing of electrons do not take place.
∵ so
(b)
Inner d-complex
If strong field ligand is available then
In
with a weak field ligand
