Which of the following descriptions about [FeCl_(6)]^(4-) is correct?

Answer»

`dsp^(3)` inner obrital COMPLEX, diamagnetic
`SP^(3)d^(2)`, outer orbital complex, paramagnetic
`d^(2)sp^(3)` inner orbital complex, paramagnetic
`sp^(3) d^(2)`, outer orbital complex , diamegnetic

Solution :In `[FeCl_(6)]^(4-)`
`Fe^(2+)(3D^(6))`

Paramagnetic due to PRESENCE of FOUR unpaired electrons.
