Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: A spectral line will be seen for a \[2{{p}_{x}}-2{{p}_{y}}\] transition. Reason: Energy is released in the form of wave of light when the electron drops from \[2{{p}_{x}}\] to \[2{{p}_{y}}\] orbital.A) If both assertion and reason are true and reason is the correct explanation of assertion
B) If both assertion and reason are true but reason is not the correct explanation of assertion
C) If assertion is true but reason is false
D) If both assertion and reason are false
Correct Answer: D
Solution :
Both the assertion and reason are false because a spectral line is observed when an electron comes back from the excited state to the ground state in one or more jump. In each jump it comes back to higher energy level to lower energy level corresponding to n = 1, 2, 3, 4...... are called K, L, M, N shells. So, shell must be changed.
