हिन्दी

Which of the following points constitute the major limitations of Bohr's model of the atom? (A) It fails to account for the finer details of the hydrogen atom spectrum observed by sophisticated spectroscopic techniques. (B) It is unable to explain the spectrum of atoms other than hydrogen, such as helium. (C) It cannot explain the splitting of spectral lines in a magnetic field (Zeeman effect). (D) It correctly explains the ability of atoms to form molecules by chemical bonds. Choose the correct answer from the options given below:

  1. (A), (C) and (D) only
  2. (B), (C) and (D) only
  3. (A), (B) and (C) only
  4. (A) and (D) only

Correct answer · Option 3

Explanation

Statements (A), (B), and (C) are correct limitations of Bohr's model. Statement (D) is false because Bohr's model could NOT explain the ability of atoms to form molecules by chemical bonds.
