The value of spin only magnetic moment for one of the following configurations is "2.84BM" .The correct one is:
\(d^{8}\) (in weak field ligand)
\(d^{4}\) (in weak field ligand)
\(d^{3}\) (in weak as well as strong field ligand)
\(d^{5}\) (in strong field ligand)

The value of the 'spin only magnetic moment for one of the following configuration is 2.84 BM. The correct one is

Velence bond theroy describes the bonding in complexs in terms of coordinate -covalent bond resulting from overlap filled ligand orbitals with vacant metal hybrid orbitals This theory explains magnetic behaviour and geometrical shape of coordination compounds Magnetic moment of a complex compound can be determined experimentally and theoretically by using spin only formula Magnetic moment sqrtn (n+2)BM (where n = No. unpaired electrons) . The value of of spin only magnetic moment for octahedral complex of the following configuration is 2.84BM The correct statement is (a) d^(4) (in weak field ligand) (b) d^(2) (in weak field and in strong field ligand) (c) d^(3) (in weak field and in strong field ligand) (d) d^(5) (in strong field ligand) .

The strong field ligand is "
