Given below are two statements: Statement I : Bohr's theory...

Given below are two statements:

Statement I : Bohr's theory accounts for the stability and line spectrum of Li+{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:

Options

  1. ABoth statement II and statement IIII are true.
  2. BStatement II is false but statement IIII is true.
  3. CBoth statement II and statement IIII are false.
  4. D

    Statement II is true but statement IIII is false.

Correct answer

B. Statement II is false but statement IIII is true.

Step-by-step solution

Statement-II is false since Bohr's theory accounts for the stability and spectrum of single electronic species ( e.g. He+,Li2+{He}^{+}, {Li}^{2 +} etc.)
Statement IIII is true.
