`[Fe(CN)_6 ]^-3` is low spin complex but `[Fe(H_2O)6]+3is high spin complex. Explain.

Low spin complexes are :

Explain that [Co(NH_3)_6]^(3+) is a low spin complex while [CoF_6]^(3-) is a high spin complex.

K_4[Fe(CN)_6] is a

[Ti (H_2O)_6]^(3+) is coloured while [Sc(H_2O)_6]^(3+) is colourless. Explain.

The name of complex [Fe(CN)_6]^(3-) is

K_3[CoF_6] is high spin complex. What is the hybrid state of Co atom in this complex ?

Explain [Fe(H_2O)_6]^(3+) is paramagnetic.

In the brown ring complex [Fe(H_2O)_5(NO)]SO_4 , nitric oxide behaves as

Fe^(3+) is more stable than Fe^(2+) . Explain.

[Fe(CN)_6]^(3-) ion has ............. unpaired electrons and [Fe(H_2O)_6]^(3+) has ............. unpaired electrons.
