Chemistry - Coordination Chemistry Question with Solution | TestHub

Question Explanation:

Question is asking incorrect statement.

Concept:

Based on C.F.T

Solution:

${\Delta }_0$ splitting energy

p = Pairing energy

Acc to C.F.T

If S.F.L present in complex than

${\Delta }_0>\mathrm{P}$ ( ${\mathrm{e}}^{-}\mathrm{s}$ are paired 1st)

If W.F.L present in complex than

${\Delta }_0<\mathrm{P}$ (Filling electrons parallelly $1^{\text{st }}$ than pairing taken place)

(4) In this option F → W.F.L. So compare should be ${\Delta }_0<\mathrm{P}$ (not ${\Delta }_0>\mathrm{P}$ ).

Final Answer: Option (D)
