Multiple choice

Directions: In the following question, there are two statements labelled as Assertion (A) and Reason (R). Mark your answer as : (a) if both A and R are true and R is the correct explanation of A. (b) if both A and R are true but R is not the correct explanation of A. (c) if A is true but R is false. (d) if A is false but R is true. (e) if both A and R are false. Assertion: Both π2px and π*2px molecular orbitals have one nodal plane. Reason: Both π2px and π*2px molecular orbitals are formed by the overlap of 2px atomic orbitals.

  1. (a)

  2. (b)

  3. (c)

  4. (d)

  5. (e)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

This option is correct because π2px has only one nodal plane while π*2px has two nodal planes. So, the assertion is false and reason is true that molecular orbitals π2px and π*2px  are formed by the overlap of 2px atomic orbitals.
