    Correct Option - 1


    Detailed Solution:

    According to Bohr’s theory,

    K . E . = 1 3 . 6 z 2 n 2 frequency ( υ ) of revolution of electron ∝ z 2 n 3

      v = 2 . 1 8 × 1 0 6 z n          

    F = k q 1 q 2 r 2 = K z e 2 r 2 ( r ∝ n 2 z )       

    F ∝ z 3 n 4

Radius of Bohr’s orbit R n = 0 . 5 2 9     A o     × n 2 z  

Radius of Bohr’s orbit for hydrogen,   R n = 0 . 5 2 9     A o     × n 2

For third orbit (R3) = 0 . 5 2 9     A o     × 9 = r3 and

Fourth orbit (R4) = 0 . 5 9     A o     × 1 6 = r 4

∴ r 4 = 1 6 r 3 9

If radius of second Bohr orbit of the He?ion is 105.8pm, what is the radius of third Bohr orbit of Li2+ ion?
V
Vishal Baghel

105.8 × (2/4) = 52.9 pm ⇒ rLi+ + rX- = 52.9 × (3²/3) = 158.7 pm

Given below are two statements:
Statement I: Bohr's theory accounts for the stability and line spectrum of Li²? 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:
R
Raj Pandey

Bohr's theory accounts for the line spectrum of single electron species but Li? has two electrons. Bohr's theory fails to explain splitting of spectral lines in presence of magnetic field i.e. Zeeman effect.
