Given below are two statements : Statement (I) : A spectral line will be observed for a 2px→2py2 \mathrm{p}_x \rightarrow 2 \mathrm{p}_y transition. Statement (II) : 2Px2 P_x and 2py2 p_y are degenerate orbitals. In the light of the above statements, choose the correct answer from the options given below :

Options

  1. ABoth Statement I and Statement II are true
  2. BStatement I is false but Statement II is true
  3. CBoth Statement I and Statement II are false
  4. DStatement I is true but Statement II is false

Correct answer

B. Statement I is false but Statement II is true

Step-by-step solution

2px2 p_{\mathrm{x}} and 2py2 \mathrm{p}_{\mathrm{y}} are degenerated orbitals hence having equal energy and therefore no spectral line will be observed for 2px→2py2 p_x \rightarrow 2 p_y transition.
