c) Between t_(2g) and e_(g) sets of d-orbitals of a central metal in an octahedral complex, which set has higher energy? |
Answer» Solution :In octahedral COMPLEX the central metal ion, surrounded.by 6 ligands. The REPULSION is more when the metal d-orbital directed TOWARDS the ligand and less when it is away from the ligands. So `d_(x^(2)-y^(2)) and d_(z^(2))` orbitals are towards the ligand. Hence they EXPERIENCE more repulsion and will be raised in energy. So they forin eq set
