# Given below are two statements:

Question:

Given below are two statements:

Statement I : Bohr's theory accounts for the stability and line spectrum of $\mathrm{Li}^{+}$ion.

Statement II : Bohr's theory was unable to explain the splitting of spectral lines in the presence of a magnetic field. In the light of the above statements, choose the most appropriate answer from the options given below:

1. Both statement I and statement II are true.

2. Statement $\mathrm{I}$ is false but statement $\mathrm{II}$ is true.

3. Both statement I and statement II are false.

4. Statement I is true but statement II is false.

Correct Option: , 2

Solution:

Statement-I is false since Bohr's theory accounts for the stability and spectrum of single electronic species $\left(\mathrm{eg}: \mathrm{He}^{+}, \mathrm{Li}^{2+}\right.$ etc $)$ Statement II is true.
