Question

Assertion : In the bonding molecular orbital (MO) of $H_2$, the 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.

• A. Assertion is incorrect, reason is correct
• B. Assertion is correct, reason is incorrect
• C. Assertion and reason are correct and reason is the correct explanation for the assertion
• D. Assertion and reason are correct, but reason is not the correct explanation for the assertion.

Answer 1

The correct option is B Assertion is correct, reason is incorrect

Bonding Molecular orbital (BMO),
${\psi }_{BMO}$ = ${\psi }_A+{\psi }_B$ which shows constructive interference of the combining electron waves.
Assertion is correct but reason is incorrect. Bonding MO shows constructive interference of the combining electron waves.
