Question

Q14.Write the drawbacks of Bohr theory​

Answer 1

Answer:

Drawbacks of Bohr's Model:

It was primarily for hydrogen atom. It couldn't elaborate spectra of multi-electron atoms. Wave nature of electron was not justified by the model (inconsistent with the de Broglie's hypothesis of dual nature of matter) It didn't illustrated molecules making process of chemical reactions.

Answer 2

Drawbacks:-

• Bohr's model of an atom could not account for the finer details of the hydrogen spectrum observed using sophisticated spectroscopic techniques.
• It could not explain line spectra of atoms containing more than one electron called multielectron atoms.
• it failed to account for the effect of magnetic field on the spectra of atoms or ions, that is splitting of spectral lines further in presence of magnetic field called as Zeeman effect.
• Similarly it could explain the effect of electric field on the spectra of atoms (known as Stark effect)
• It could not provide clue to explain the shapes of molecules arising out of the directional bonding between atoms.
