Given below are two statements : Statement (I) : A spectral line will be observed for a 2p_x → 2p_y transition. Statement (II) : 2p_x and 2p_y are degenerate orbitals. In the light of the above statements, choose the correct answer from the options given below : (1) Both Statement-I and Statement-II are true. (2) Both Statement-I and Statement-II are false. (3) Statement-I is true but Statement-II is false. (4) Statement-I is false but Statement-II is true.

1. Both Statement-I and Statement-II are true.
2. Both Statement-I and Statement-II are false.
3. Statement-I is true but Statement-II is false.
4. Statement-I is false but Statement-II is true.

Correct answer: Statement-I is false but Statement-II is true.

Solution

Statement I is false because a transition between degenerate orbitals like 2p_x and 2p_y does not result in a spectral line due to the lack of energy difference, while Statement II is true as 2p_x and 2p_y are indeed degenerate orbitals.
