State the limitations of Werner's coordination theory.

(N/A) Werner's theory could not explain the following:
$1$. The directional properties of bonds in coordination compounds.
$2$. The ability of certain elements to form coordination compounds.
$3$. The magnetic and optical properties of coordination compounds.
The nature of bonding in coordination compounds is better explained by Valence Bond Theory $(VBT)$,Crystal Field Theory $(CFT)$,Ligand Field Theory $(LFT)$,and Molecular Orbital Theory $(MOT)$.
