Write the limitations of Valence Bond Theory.
The limitations of valence bond theory are: (i) VBT fails in explaining the tetravalency of carbon. (ii) The geometries of ammonia, water, methane, etc cannot be properly explained by this theory. (iii) Bond angles of molecules such as carbon dioxide, water, ammonia, etc could not properly be given by VBT. (iv) VBT does not explain the magnetic properties of complex.
