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

Both Assertion and Reason are true and Reason is the correct explanation of Assertion

B

Both Assertion and Reason are true but Reason is not a correct explanation of Assertion

C

Assertion is true but Reason is false

D

Assertion is false but Reason is true

Text Solution

Verified by Experts

The correct Answer is:
D
There is no difference in energy level between `2p_x` and `2p_y` therefore , no spectral lines will form . Hence, assertion is incorrect.
