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.
