Which of the following statements is correct for the `[Fe(H_(2)O)_(5)NO]SO_(4)` complex ? .

Options

A. The `EAN` value of Fe in this complex depends on the charge of `NO` ligand .
B. The `EAN` value of Fe in this complex depends on the charge of `NO` ligand .
C. The hybridisation of the central atom is `d^(2)sp^(3)` .
D. It is paramagnetic with `mu = 1.73BM` .

Answer

B

Explanation

`[Fe(H_(2)O)_(5)(NO)]^(2+)`
Hybridisation `sp^(3)sp^(2) (n =3), mu_(eff) 3.89 BM`
Inspite of electronic transition from `NO` to `Fe^(2+)` total number of electrons remain conserved Hence `EAN` does not change .
