Assertion: Both π(2 p_x) and π^*(2 p_x) MO's have one nodal plane...

Assertion: Both π(2px)\pi\left(2 p_x\right) and π∗(2px)\pi^*\left(2 p_x\right) MO's have one nodal plane each. Reason: All MO's formed by side way overlapping of 2p2 p-orbitals have one nodal plane.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

π(2px)\pi\left(2 p_x\right) has one nodal plane whereas π∗(2px)\pi^*\left(2 p_x\right) has two nodal planes.
