Correct answer: A. Both Statement I and Statement II are correct

In an octahedral crystal field, the five degenerate d-orbitals split into two sets: a lower energy

t_{2g}

set and a higher energy

e_g

set.

The energy of the

t_{2g}

orbitals is lowered by

0.4\Delta_o

(stabilization of

-0.4\Delta_o

) and the energy of the

e_g

orbitals is raised by

0.6\Delta_o

(destabilization of

+0.6\Delta_o

) relative to the barycenter. Hence, Statement I is correct.

In the free atomic or ionic state, all five d-orbitals of a transition metal are degenerate (have the same energy). When ligands approach the central metal ion to form a complex, the spherically symmetrical field is disrupted, which destroys the degeneracy of the d-orbitals and causes them to split. Hence, Statement II is correct.

Both Statement I and Statement II are correct.
