MCQ
The Bohr model for the spectra of a H-atom:
  • A
    Will not be applicable to hydrogen in the molecular from.
  • B
    Will not be applicable as it is for a He-atom.
  • A and B both
  • D
    Predicts continuous as well as discrete spectral lines.

Answer

Correct option: C.
A and B both
​​​​​​​Solution:
Bohr proposed a-model for hydrogen atom which is also applicable for some lighter atoms in which a single electron revolves around a stationary nucleus of positive charge Ze (called hydrogen like atom, e.g., $\mathrm{H}, \mathrm{He}^{+}, \mathrm{Li}^{+2}, \mathrm{Na}^{+1}$ etc). It is not applicable to hydrogen in the molecular form and also, it will not be applicable as it is for a He-atom.
