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

Options

A. 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
B. 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
C. Both points (A) and (B) correct
D. Both points (A) and (B) are wrong .

Answer

C

Explanation

CFSE in case of tetrahedral complexes is less than the octahedral field due to both the points A and B.
