The bhor model for the spectra of H-atom

will not be applicable to hydrogen in the molecular form

will not be applicable as it is for a H-atom

is valid only at room temperature

predicts continuous as well as discrete spectral lines

Text Solution

Verified by Experts

The correct Answer is:

A, B

Bohr model for the spectra of H-atom is not applicable to hydrogen in the molecular form. As its 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.
