Question

Assertion :$N_{2}O$ is represented by $\left(i\right)$ $N=N=O$ and $\left(ii\right)$ $N\equiv N\to O$ but later is more stable. Reason: The form $\left(ii\right)$ shows resonance.

• 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 C Assertion is correct but Reason is incorrect

Option (C) is correct.
$N\equiv N\to O$ is more stable due to lesser formal charge on N-atom.
They're resonance structures but the one with the negative charge on the oxygen is more favorable because oxygen is a highly electronegative atom, and is more electronegative than nitrogen.It likes electrons more than nitrogen. Therefore, $N\equiv N\to O$ is more favorable and stable.
