Question

Given below are two statements:

Statement I: In octahedral complexes, when  high spin complexes are formed. When  low spin complexes are formed.

Statement II: In tetrahedral complexes because of , low spin complexes are rarely formed.

Strategy:
 Understand the competition between Crystal Field Splitting Energy () and Pairing Energy () in both geometries.

Step 1: Evaluate Statement I (Octahedral)
- If : It costs more energy to pair electrons than to place them in the higher  orbitals. Electrons spread out according to Hund's rule, creating high spin complexes.
- If : The splitting is enormous. It costs less energy to pair electrons in the lower  orbitals than to ascend to , creating low spin complexes.
(Statement I is true).
