JEE MAIN - Chemistry (2020 - 6th September Evening Slot - No. 11)
For a d4 metal ion in an octahedral field, the
correct electronic configuration is :
$$t_{2g}^4e_g^0$$ when $$\Delta $$0 < P
$$t_{2g}^3e_g^1$$ when $$\Delta $$0 > P
$$e_g^2t_{2g}^2$$ when $$\Delta $$0 < P
$$t_{2g}^3e_g^1$$ when $$\Delta $$0 < P

back pairing is not possible
because pairing energy > $$\Delta $$0.
