Given below are two statements: Statement I: Each electron in e_g orbitals destabilizes the orbitals by +0.6 _o and each electron in the t_ 2g orbitals stabilizes the orbitals by -0.4 _o in an octahedral field on the basis of crystal field theory. Statement II: All the d-orbitals of the transition metals have the same energy in their free atomic state but when a complex is formed the ligands destroy the degeneracy of

Step-by-step solution

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 _o (stabilization of -0.4 _o ) and the energy of the e_g orbitals is raised by 0.6 _o (destabilization of +0.6 _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
