Assertion : Aspectral line will be seen ...

Assertion : Aspectral 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.

A

If both (A) and (R) are correct and (R) is the correct explanation of(A).

B

If both (A) and (R) are correçt, but (R) is not the correct explanation of (A).

C

If (A) is correct, but (R) is incorrect.

D

If both (A) and (R) are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
D
No spectral line is observed for `2p_(x)-2p_(y)` transition. No energy is released when electron drops from `2p_(x)` to `2p_(y)` (because they are degenerate orbitals).
