Question

Which of the following pair of complexes have the same EAN of the central metal atoms/ions?

Solution

Correct option is

All

 

EAN of Fe in (Fe(CN)6]3– = 26 – 3(O.N) + 6 × 2 = 35  

EAN of Fe in [Fe(CN)6]4– = 26 – 2(O.N) + 6 × 2 = 36  

EAN of Co in (Co(NH3)6]3+ = 27 – 3(O.N.) + 6 × 2 = 36

EAN of Cr in [Cr(CrO4)3]3– = 24 – 3(O.N) + 3 × 4 = 33     

EAN of Cr in [Cr(NH3)4]3+ = 24 – 3(O.N) + 6 × 2 = 33
