Q.72 Given below are two statements Statement I : According to Bohr's model of hydrogen atom, the angular momentum of an electron in a given stationary state is quantised. Statement II : The concept of electron in Bohr's orbit, violates the Heisenberg uncertainty principle. In the light of the above statements, choose the most appropriate answer from the options given below

1. Statement I is incorrect but Statement II is correct
2. Both Statement I and Statement II are correct
3. Both Statement I and Statement II are incorrect
4. Statement I is correct but Statement II is incorrect

Correct answer: Both Statement I and Statement II are correct

Solution

Statement I is correct because Bohr's model indeed quantizes the angular momentum of electrons in specific orbits. Statement II is also correct as the fixed position and momentum of electrons in Bohr's orbits contradict the Heisenberg uncertainty principle, which states that we cannot precisely know both position and momentum simultaneously.
