After understanding the assertion and reason, choose the correct option. Assertion: In the bonding molecular orbital (MO) of H 2 , electron density is increased between the nuclei. Reason: The bonding MO is ψ A + ψ B , which shows destructive interference of the combining electron waves.

Options

  1. AAssertion and Reason are correct, but Reason is not the correct explanation for the Assertion.
  2. BAssertion and Reason are correct and Reason is the correct explanation for the Assertion.
  3. CAssertion is incorrect, Reason is correct.
  4. DAssertion is correct, Reason is incorrect.

Correct answer

D. Assertion is correct, Reason is incorrect.

Step-by-step solution

Electron density between nuclei increased during formation of BMO in H 2 . BMO is ψ A + ψ B (Linear combination of Atomtextc orbitals) provides constructive interference. While by distructive interference anti BMO ψ A − ψ B formed.
