Question

Given following complexes 

(I) Na₄[Fe(CN)₆] 

(II) [Cr(H₂O)₆] Cl₂ 

(III) (NEt₄)₂ [CoCl₄] 

(IV) Na₃[Fe(C₂O₄)₃] (Δ₀ > P) 

Correct order of spin only magnetic moment for the above complexes is

(1) (II) > (III) > (IV) > I 

(2) (II) > (IV) > (III) > (I) 

(3) (I) > (IV) > (III) > (II) 

(4) (II) > (I) > (IV) > (III)

Answer 1

The answer is (1) (II) > (III) > (IV) > I
