Assertion. A spectral line will be seen for a 2p_(x) - 2p_(y) transition Reason. Energy is released in the form of waves of light when the electron drops from 2p_(x) " to " 2p_(y) orbital

Answer»

If both assertion and REASON are true, and reason is the true explanation of the arrertion
If both assertion and reason are true, but reason is not the true explanation of the assertional
If assertion is true, but reason is false
If both assertion and reason are false

Solution :CORRECT A. No spectral LINE is observed for `2p_(x) - 2p_(y)` transition
Correct R. No energy is RELEASED when ELECTRON drops from `2p_(x) " to " 2p_(y)` (because they are degenerate orbitals)
