LIMITATIONS -
1) Bohr model could not explain the spectra of atons containing more than one electrons
2) it could not explain the splitting of spectral lines in the presence of magnetic field (ZEEMAN'S EFFECT ) and electric field (STARK'S EFFECT)
3) it treated electrons as particles and ignored the dual behaivior of electrons
4) it contradicts Heisenberg's uncertainty principle and is therefore not valid as according to bohr's model electrons have well defined paths called orbits .
5) it couldn't explain the ability of atoms to form molecules and the geometry and shapes of molecules

Limitations of Neils Bohr model of atoms:
1. Bohr's model explained structure and some observed properties of Hydrogen atom. But it could not explain those of larger atoms.
Spectral lines of radiations emitted by Hydrogen in presence of magnetic fields weren't explained. Spectral lines of atoms with more than 1 electron aren't explained well.
2. Bohr's model says electrons rotate around the nucleus. But it's then expected that electrons lose energy while rotating around in orbits. Lost energy is emitted as radiation. They should gradually fall into nucleus. But it doesn't happen.
3. Heisenberg's uncertainty principle and theory is not explained by Bohr's model.
4. Wave and particle dual behavior of electrons is not explained by Bohr's model.
Bohr's model explained very well a basic structure of atom. That was the foundation of many advanced and correct theories. Bohr's theory was based on the experiments done at that time.
