Question

The correct charge on and co-ordination number of 'Fe' in K₃[Fe(CN)₆] is ______.

विकल्प

• +2, 4 

• +3, 6

• +2, 6 

• +3, 3

Answer 1

+3, 6

Explanation:

Coordination number of Fe in K₃[Fe(CN)₆] is 6 as it is bonded with six CN ligands.

Let x be the oxidation state of Cr

∴ x + 6(- 1) = - 3

∴ x = + 3
