Chemistry - Carbonyl compounds Question with Solution | TestHub

The given value of$\mathrm{\mu }$(spin only)
$\mathrm{\mu }=\sqrt{(\mathrm{n}+2)}\mathrm{n}$
$2.84=\sqrt{\mathrm{n}(\mathrm{n}+2)}$BM
So, n = 2.
Among the given configurations,${\mathrm{d}}^4$system in strong ligand field will have 2-unpaired${\mathrm{e}}^{-}$in${\mathrm{t}}_2\mathrm{g}$set of orbitals as shown below
