Solution

The correct option is C 2
Magnetic moment $= \sqrt{n (n + 2)}$ where n is no. of unpaired electrons.
$\sqrt{n (n + 2)} = 2.8$ , $n = 2$ .

Valence bond theory describes the bonding in complexes in terms of coordinate-covalent bonds resulting from the overlap of filled ligand orbitals with vacant metal hybrid orbitals. This theory explains the magnetic behavior and geometrical shape of coordination compounds. The magnetic moment of a complex compound can be determined experimentally and theoretically by using spin only formula.
