Question

Assertion :$F_2$ and $O_2^{2-}$ have bond order 1 while $N_2,CO$ and $N{O}^{+}$ have bond order 3. Reason: Higher the bond order, higher is the stability of the molecule.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion

Correct reason

$F_2$ and $O_2^{-}2$ have $10$ electrons in $BMO$ and $8$ electrons in $ABMO$,

$N_2,CO$ and $N{O}^{+}$ have $10$ electrons in $BMO$ and $4$ electrons in $ABMO$,

So the correct option is [B].
