When a transition metal ion (usually) is involved in octahedral complex formation, the five degenerate d-orbitals split into two set of degenerate orbitals (3+2) . Three degenerate orbitals of lower energy (d_(xy),d_(yz),d_(zx)) and a set of degenerate orbitals of higher energy (d_(x^(2)-y^(2)" and "d_(z^(2)) . The orbitals with lower energy are called t_(2g) orbitals and those with higher energy are called e_(g) orbitals. In octahedral complexes, positive metal ion may be considered to be present at the centre and negative ligands at the corner of a regular octahedron. As lobes of d_(x^(2)-y^(2)" and "d_(z^(2) lie along the axis, i.e., along the ligands, the repulsions are more and so, high is the energy. The lobes of the remaining three d-orbitals lie between the Axis i.e., between the ligands. The repulsions between them are less, so lesser the energy. In the octahedral complexes, if metal ion has electrons more than 3, then for pairing them, the options are (i) Pairing may start with 4th electron in t_(2g) orbitals. (ii) Pairing may start normally with 6th electron when t_(2g)" and "e_(g) orbitals are singly filled. In which of the following configurations, hybridisation and magnetic moment of octahedral complexes are independent of nature of ligands. (P) d^(3) configuration of any metal cation (Q) d^(6) configuration of IIIrd transition series metal cation (R ) d^(8) configuration of Ist transition series metal cation (S) d^(7) configuration of any metal cation Select the correct code:
