Question

Write the geometry and magnetic behaviour of the complex [Ni(CO)\(_4\)] on the basis of Valency Bond Theory (VBT).

Hint:

- In tetrahedral complexes, the central metal atom undergoes sp\(^3\) hybridization. - Diamagnetic behavior is observed when all electrons are paired, and there are no unpaired electrons in the system.

Answer 1

The compound [Ni(CO)\(_4\)] exhibits tetrahedral geometry. In accordance with Valency Bond Theory (VBT), the central metal ion, Nickel (Ni), undergoes sp\(^3\) hybridization to establish four coordinate bonds with the carbon monoxide (CO) ligands. This complex is classified as diamagnetic because all electrons present within the CO ligands are paired.
