Magnetic moment, $\mu =\sqrt{n\left(n+2\right)} =5.92\mathrm{BM}$

Hence, number of unpaired electrons, $\mathrm{n}=5$

As the complex mentioned is high spin, electronic configuration should be ${\mathrm{t}}_{2\mathrm{g}}^3{\mathrm{e}}_{\mathrm{g}}^2$.

As no pairing of electrons takes place against hund's rule,

pairing energy$>{∆}_o$
