Question

Which of the following statements are correct?
(i) In octahedral complexes, $d_{z}2, d_{x^{2}-y^{2}}$ orbitals have higher energy than $d_{xy} . d_{yz}$ and $d_{yz}$ orbitals.
(ii) In tetrahedral complexes, $d_{xy}, d_{yz} d_{zx}$ da orbitals have higher energy than $d_{z}2$ and $d_{x^{2}-y^{2}}$ orbitals.
(iii) The colours of complexes are due to electronic transitions from one set of (/-orbitals to another set of orbitals.
(iv) $\Delta_{tetrahedm} =\frac{9}{4} \Delta_{0ctahedral}$
