Select one: a. 7 b. 8 c. 4 d. 5 e. 6
Explanation / Answer
According to Crystal field theory, in octahedral complexes five (n 1)d orbitals with ligands arranged in a regular arrangement around a transition-metal ion.
These five d orbitals split into two groups: in the first group two orbitals dz2 and dx2y2 are point directly at the six negative charges located on the x, y, and z axes with the higher energy electrons and in second group three orbitals dxy, dxz, and dyz, (collectively called the t2g orbitals.) are oriented between the six negative charges with the lower energy electrons.
Thus the option d is correct answer.
