The Bohr model for the spectra of a H-atom:

a. will not be applicable to hydrogen in the molecular form.
b. will not be applicable as it is for a He-atom.
c. is valid only at room temperature.
d. predicts continuous as well as discrete spectral lines.

1. (a, b)
2. (c, d)
3. (b, c)
4. (a, d)

(1) Hint: The Bohr model is only applicable to H-like atoms.
The Bohr model for the spectra of a H-atom will not be applicable to hydrogen in the molecular form. And also, it will not be applicable as it is for a He-atom.
