Problem: The N - N bond length in N2O is 1.12 Å, slightly longer than a typical N≡N bond, which is 1.10 Å, and the N - O bond length is 1.19 Å, slightly shorter than a typical N = O bond, which is 1.22 Å. Based on these data, which resonance structure best represents N2O?

🤓 Based on our data, we think this question is relevant for Professor Bindell's class at UCF.

FREE Expert Solution

We are asked which resonance structure best represents N2O


Recall: More pi bonds → shorter and stronger bond


N - N bond length → slightly longer than a typical N≡N bond 

N - O bond length → slightly shorter than a typical N = O bond
