A) 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
B) the direction of the orbitals does not coincide with the direction of the ligands. This reduces the crystal field stabilisation energy \[({{\Delta }_{t}})\] by further 2/3
C) both points a and b are correct
D) both points a and b are wrong
Correct Answer: C
Solution :
In tetrahedral complexes, there are only four ligands whereas in octahedral complexes, six ligands are observed. Therefore, tetrahedral complexes show only 2/3 size than octahedral complexes, hence \[\Delta t\] is only 2/3 of the size. Also the direction of the orbitals does not coincide with the direction of the ligands. This reduces the crystal field stabilisation energy \[({{\Delta }_{t}})\] by further 2/3.You need to login to perform this action.
