Question

Given below are two statements:
Statement I: Rutherford's gold foil experiment cannot explain the line spectrum of hydrogen atom.
Statement II: Bohr's model of hydrogen atom contradicts Heisenberg's uncertainty principle.
In the light of the above statement, choose the most appropriate answer from the options given below:

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

Answer 1

The correct option is D Both statement I and statement II are true

One of the drawback of Rutherford model is that, it says nothing about the electronic structure of atom. It cannot explain the line spectra of hydrogen atom.

Since uncertainty principle rules of existence of definite paths of trajectories of particles like electrons. So Bohr's model contradicts H.U.P.
Option (d) is the correct answer.
