Question:

After understanding the assertion and reason, choose the correct option.
Assertion: In the bonding molecular orbital (MO) of \(\mathrm{H_2}\), electron density is increased between the nuclei.
Reason: The bonding MO is \(\psi_A + \psi_B\), which shows destructive interference of the combining electron waves.

Show Hint

The bonding MO arises from constructive (in-phase) interference.

  • Assertion and Reason are correct, but Reason is not the correct explanation for the Assertion.
  • Assertion and Reason are correct and Reason is the correct explanation for the Assertion.
  • Assertion is incorrect, Reason is correct.
  • Assertion is correct, Reason is incorrect.

The Correct Option is D

Solution and Explanation

Assertion: in the bonding MO the wave functions add, which piles up electron density between the two nuclei, so the Assertion is correct.
Reason: the combination \(\psi_A + \psi_B\) is the in-phase (additive) overlap, i.e. constructive interference, not destructive. So the Reason is incorrect.
Answer: (4) Assertion is correct, Reason is incorrect.
