The correct charge on and co-ordination number of `'Fe'` in `K_(3)[Fe(CN)_(6)]` is

A

`+2,4`

B

`+3,6`

C

`+2,6`

D

`+3,3`

Text Solution

Verified by Experts

The correct Answer is:
B
Coordination number of Fe in `K_(3) [Fe(CN)_(6)]` is 6 because it is bonded with six CN ligands.
Let x be the oxidation state of Cr
`:. x + 6 (-1)= - 3`
`:. x = + 3`
