The magnitude of crystal field stabilization energy (CFSE) in tetrahedral complexes is considerably less than in the octahedral field beause

There are only four ligands instead of six so the ligand field is only `2//3` the size hence the `Delta_(t)` is only `2//3` the size

The direction of the orbitals does not coincide with the direction of the ligands. This reduces the crystal field stabilization energy `Delta_(t)` by further `2//3` .

Both points (1) and (2) are correct

Both points (1) and (2) are wrong

Text Solution

Verified by Experts

The correct Answer is:

In tetrahedral cooordination entity formation, the d - orbitals splitting is smaller as compared to the octahedral field splitting because there arer only four ligands instead of six and the apprach of ligands is in between the axes instead of along the axes.

The magnitude of crystal field stabilization energy (CFSE or Delta t) in tetrahedral complexes is considerably less than in octahedral field. This is because

There are four ligands instead of six so the ligand field is only 2/3 the size hence , the `Delta`t is only 2//3 the size

The direction of the orbitals does not coincide with the direction fo the ligands . This reduces the crystal field stabilisation energy `(Deltat)` by further 2/3
