Answer 1

Coordination number of Fe in K₄[Fe(CN)₆] is 6.

Explanation:

The coordination number of Fe in K₄[Fe(CN)₆] is 6 because the central Fe³⁺ ion is coordinated to six cyanide (CN⁻) ligands. Each CN⁻ is a monodentate ligand, meaning it forms one coordinate bond with the metal ion. Since there are six CN⁻ ligands, the coordination number of Fe is 6, leading to an octahedral geometry around the Fe ion.
