Write the limitations of Valence Bond Theory $(VBT)$.

(N/A) $VBT$ can explain the formation,structure,and magnetic behavior of coordination compounds. However,it has the following limitations:
$(i)$ It involves a number of assumptions.
$(ii)$ It does not give a quantitative interpretation of magnetic data.
$(iii)$ It cannot explain the color exhibited by coordination compounds.
$(iv)$ It does not give a quantitative interpretation of the thermodynamic or kinetic stability of coordination compounds.
$(v)$ It does not make exact predictions regarding the tetrahedral and square planar structures of $4$-coordinate complexes.
$(vi)$ It does not distinguish between weak and strong ligands.
