Question

Assertion :A spectral line will be seen for 2p${}_x$ - 2p${}_y$ transition. Reason: Energy is released in the form of wave of light when the electron drops from 2p${}_x$ to 2p${}_y$ orbital.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is D Both Assertion and Reason are incorrect

All p orbitals have same energy, they only have different orientation so no energy will be released when the electron drops from 2p${}_x$ to 2p${}_y$ orbital and we didn't found any spectral line for that.
