Crystal Field Splitting in Octahedral Complexes

When degenerate d-orbitals of an isolated atom/ion come under influence of magnetic field of ligands, the degeneray is lost. The two set t_(2g)(d_(xy),d_(yz),d_(xz)) and e_(g) (d_(x^(2))-d_(x^(2)-y^(2)) are either stabilized or destabilized depending upon the nature of magnetic field. it can be expressed diagrammatically as: Value of CFSE depends upon nature of ligand and a spectrochemical series has been made experimentally, for tetrahedral complexes, Delta is about 4/9 times to Delta_(0) (CFSE for octahedral complex). this energy lies in visible region and i.e., why electronic transition are responsible for colour. such transition are not possible with d^(0) and d^(10) configuration. Q. The extent of crystal field splitting in octahedral complexes of the given metal with particular weak field ligand are:

STATEMENT-1: Tetrahedral complexes are always high spin complexes . STATEMENT-2: Crystal field splitting energy in tetrahedral complexes is 2/3 of the Delta_(0) (crystal field splitting energy in octahedral complexes). STATEMENT-3: Tetrahedral complex [MABCD]^(pm n) is optically active .

In crystal field splitting for a tetrahedral complex, the number of orbitals pushed down in energy are

Crystal Field Splitting in Tetrahedral and Square Planar Field || Comparision OF CFSE || Factors Effecting CFSE

What factor determines whether the crystal field in an octahedral complex is to be regarded as strong or weak? How many d-electrons must be present in orbitals of the central atom atom for there to be an abrupt change in crystal field stabilisation energy strong and weak fields gt
