What are the limitations of Bohr's theory of hydrogen atom?

i) Bohr's model could not explain the spectra of complex atoms of multi electronic systems.
ii) It could not explain the difference in the intensities of emitted radiations.
iii) It could only partially explain hydrogen atom. For example, this theory does not explain the fine structure of spectral lines in the hydrogen atom.
iv) It could not explain experimentally observed phenomena such as Zeeman effect, Stark effect etc.
v) It is silent about the wave properties of electrons.
vi) Bohr's model does not explain why the orbits are circular while elliptical orbits are also possible.
