Inspite of the capacity to explain the formation of complex compounds, Werner's theory is having many defects. Some o£ the important drawbacks are enumerated here.
i. Werner's theory does not correlate electronic configuration of the central metal with the formation of the complex compounds. Now it is known that the central metals try to acquire the next inert gas structure through coordinate bond formation. Hence complexes are formed.
ii. The postulates of Werner do not offer any explanation to the colour of the complex compounds. It is appropriate at this juncture, to know how the d - d transition take place and result in the colour to the complex.
iii. Werner's theory is incapable of explaining the magnetic behaviour. We know that the magnetic property depends on the number of unpaired electrons present in the metal ion; Werner's theory is not related to electronic configuration and so this property could not be explained.

bohrs theory holds that each atom consists of a small, dense, positively charged nucleus surrounded by negatively charged electrons that move in fixed, defined orbits about the nucleus, the total number of electrons normally balancing the total positive charge of particles in nucleus.
Pioneers of modern quantum theory include Albert Einstein, Max Planck, Niels Bohr, Max Born, Werner Heisenberg, Erwin Shroedinger, Paul Dirac, Wolfgang Pauli, Richard Feynman, and quite a few other physicists and mathematicians.

Werner's theory, proposed by Alfred Werner in 1893, was the first attempt to explain the bonding in coordination compounds. It suggested that metal ions can form coordination complexes by donating electron pairs to coordinate covalent bonds with surrounding ligands. This theory laid the foundation for modern coordination chemistry.
