Question

Assertion :Bond order for $N_2^{+}$ and $N_2^{-}$ are same but $N_2^{+}$ is more stable than $N_2^{-}$. Reason: Anitbonding electrons are more in $N_2^{-}$.

• 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. Assertion is incorrect but reason is correct

Answer 1

The correct option is A Both Assertion and reason are correct and Reason is the correct explanation for assertion

Bond order for $N_2^{+}$ and $N_2^{-}$ are same i.e $2.5$ but $N_2^{+}$ has more electrons in anitbonding molecular orbital ,thus $N_2^{+}$ is more stable than $N_2^{-}$.
