  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

Answer:

  Bohr model for the spectra of H-atom is not applicable to hydrogen in the molecular form. As it is, the Bohr model is not applicable to a He atom. These are the known limitations of Bohr atom model. Choices (a) and (b) are correct
