Assertion (A) : A spectral line will be ...

Assertion (A) : A spectral line will be seen for `2p_(x)`-`2p_(y)` transition
Reason (R ) : Energy is raleased in the form of wave of light when the electron drops from `2p_(x)` , to `2p_(y)` orbital.

A

If both assertion and reason are true, and reason is the true explanation of the arrertion

B

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

C

If assertion is true, but reason is false

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
D
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)
