Question

Given below are two statements :
Statement I : Bohr's theory accounts for the stability and line spectrum of $L{i}^{+}$ 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:

• A. Both statement I and statement II are true.
• B. Statement I is false but statement II is true.
• C. Both statement I and statement II are false.
• D. Statement I is true but statement II is false.

Answer 1

Answer: (B)

Statement-I is false since Bohr's theory accounts for the stability and spectrum of single electronic species $(eg:H{e}^{+},L{i}^{2+}$ etc) Statement II is true.
