In which structure crystal field splitting energey `(CFSE)` for octahedral complex will be zero when `DeltaltP` .

A

`-1.0Delta_(t)`

B

`1.0Delta_(t)`

C

0

D

`-1.8Delta_(t)`

Text Solution

Verified by Experts

The correct Answer is:
c
Tetrahedral complex , `CN =4`
`(Delta lt P "weak ligand no pairing high spin")`
`Fe = 3d^(6) 4s^(2), Fe^(+3) = 3d^(5)` Structure is `(e^(2) t_(2)^(3))`
`CFSE = - 0.6 xx 2 + 0.4 xx 3 = 0` .
