State the limitations of crystal field theory $(CFT)$.

(N/A) Although the crystal field theory successfully explains the formation of structures,color,and magnetic properties of coordination compounds,it has the following limitations:
$1$. $CFT$ is based on an electrostatic model where metal ions and ligands are assumed to be point charges. Hence,it cannot explain the covalent character of the $M-L$ bond.
$2$. Anionic ligands are assumed to be point charges and thus should exert the maximum splitting effect. However,anionic ligands are actually found at the low end of the spectrochemical series.
$3$. It does not account for the $\pi$-bonding in coordination complexes.
The limitations of $CFT$ are explained by Ligand Field Theory $(LFT)$ and Molecular Orbital Theory $(MOT)$.
