Why are low spin tetrahedral complexes not formed ?

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Understanding Tetrahedral Complexes**: - Tetrahedral complexes are formed when a central metal atom is surrounded by four ligands at the corners of a tetrahedron. - The geometry leads to a specific arrangement of d orbitals, which undergoes splitting due to the presence of ligands. 2. **D Orbital Splitting**: - In tetrahedral complexes, the d orbitals split into two sets: the lower energy set (e) and the higher energy set (t2). ...
