For the complex ion [Fe (CN) 6]3- , state (1) The type of hybridisation. (2) The magnetic behaviour (3) The oxidation number of the central metal atom.

Answer:

Consider a complex [Fe(CN)₆]⁻³

CN is a powerful field ligand and uses inner 3d-orbitals to form a low spin complex. Because there are 6 ligands, it has octahedral geometry. So the hybridization of the complex is d²sp³.

The electronic configuration of central metal ion Fe is

Fe (26) = [Ar] 4s² 3d⁶

Fe³⁺ = [Ar] 3d⁵4s⁰

The central metal has an oxidation number +3 calculated as:

x + 6 × (−1) = −3

(1) Hybridization – d2sp3

(2) Magnetic behaviour – Paramagnetic in nature

(3) The oxidation state of Fe = -3
