BITSAT Chemistry Question (2023) — Solution

Question

If the radius of the 3 rd Bohr's orbit of hydrogen atom is r_3 and the radius of 4^ th Bohr's orbit is r_4. Then:

Options

  1. A. r_4= 9 16 r_3
  2. B. r_4= 16 9 r_3
  3. C. r_4= 3 4 r_3
  4. D. r_4= 4 3 r_3

Answer

B. r_4= 16 9 r_3

Step-by-step solution

aligned & r=0.529 n^2 Z Å \\ & r_3=0.529 3^2 1 r_4=0.529 4^2 1 \\ & r_4 r_3 = 4^2 3^2 = 16 9 r_4= 16 r_3 9 aligned
