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

Options

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. Both assertion and reason are false

Explanation

To solve the assertion and reason question, we need to analyze both the assertion (A) and the reason (R) provided.

### Step 1: Analyze the Assertion (A)
The assertion states that a spectral line will be seen for the transition from the `2p_(x)` orbital to the `2p_(y)` orbital.

- **Understanding the Orbitals**: The `2p` orbitals (i.e., `2p_(x)`, `2p_(y)`, and `2p_(z)`) are degenerate, meaning they have the same energy level.
- **Transition**: For a spectral line to be observed, there must be a change in energy when an electron transitions from one orbital to another. Since `2p_(x)` and `2p_(y)` are of the same energy, there is no energy difference during this transition.

**Conclusion for Assertion**: The assertion is **false** because no spectral line will be observed for the transition between `2p_(x)` and `2p_(y)` due to their equal energy levels.

### Step 2: Analyze the Reason (R)
The reason states that energy is released in the form of a wave of light when the electron drops from the `2p_(x)` to the `2p_(y)` orbital.

- **Energy Release**: For energy to be released as light, there must be a transition between orbitals of different energy levels. Since `2p_(x)` and `2p_(y)` are degenerate, the transition does not involve a change in energy.
- **Conclusion for Reason**: The reason is also **false** because no energy is released in this transition, as there is no energy difference.

### Final Conclusion
Both the assertion and the reason are false.

### Answer:
**Both Assertion (A) and Reason (R) are false.**
