Question

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

easy

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
