Define EAN. Calculate the EAN of the following metals in their respective complexes: [Cu(NH_3)_4](OH)_2 and K_4[Fe(CN)_6]

Assertion: [Fe(CN)_6]^(3-) is weakly paramagnetic while [Fe(CN)_6]^(4-) is diamagnetic Reason: Both [Fe(CN)_6]^(3-) and [Fe(CN)_6]^(4-) involve d^2sp^3 hybridisation. In [Fe(CN)_6]^(3-) singly occupied d-orbital is available but in [Fe(CN)_6]^(4-) paired electrons are present

Valence bond theory successfully explains the magnetic behaviour of complexes. The substances which contains unpaired electrons are paramagnetic and paramagnetic character increases as the number of unpaired electrons increases. Magnetic moment of a complex can be determined experimentally and by using formula sqrt(n(n+2)) and we can determine the number of unpaired electrons in it. This information is important in writing electronic structure of complex which in turn also useful in deciding the geometry of complex. Which of the following are diamagnetic ? 1) K_(4)[Fe(CN)_(6)] 2) K_(3)[Cr(CN)_(6)] 3) K_(3)[Co(CN)_(6)] 4) K_(2)[Ni(CN)_(4)]
