(N/A) The limitations of valence bond theory are:
$1$. It involves a number of assumptions.
$2$. It does not give quantitative interpretation of magnetic data.
$3$. It does not explain the colour exhibited by coordination compounds.
$4$. It does not give a quantitative interpretation of the thermodynamic or kinetic stabilities of coordination compounds.
$5$. It does not make exact predictions regarding the tetrahedral and square planar structures of $4$-coordinate complexes.
$6$. It does not distinguish between weak and strong ligands.
