Point to be covered -Crystal Field Theory (CFT)
Crystal Field Theory is a model that explains the electronic structure and properties of transition metal complexes.

Key Points:
- *Splitting of d-orbitals*: In an octahedral complex, the d-orbitals split into two groups: t₂g (dxy, dyz, dzx) and eg (dx²-y², dz²).
- *Crystal field splitting energy (Δ)*: The energy difference between t₂g and eg orbitals.
- *High-spin and low-spin complexes*: Depending on Δ, electrons can occupy orbitals in different ways, leading to high-spin or low-spin complexes.
- *Stability of complexes*: CFT explains the stability of complexes based on the number of electrons and Δ.

Applications:
- *Color of transition metal complexes*: CFT explains the colors of complexes based on d-d transitions.
- *Magnetic properties*: CFT predicts the magnetic behavior of complexes.
- *Geometries of complexes*: CFT explains the geometries of complexes.
