Question

Assertion : A spectral line will be observed for a $2 p_{x}-2 p_{y}$ transition.
Reason: The energy is released in the form of wave of light when electron drops from $2 p_{x}$ to $2 p_{y}$ orbital.

• A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
• B. If both Assertion and Reason are true but the reason is not the correct explanation of the Assertion
• C. If Assertion is true but Reason is false
• D. If both Assertion and Reason are false

Answer 1

Answer: (D)

Since the $2 p_{x}$ and $2 p_{y}$ orbitals are degenerate orbitals, ie, are of equal energy, so there is no possibility of electron transition.
