The following three Lewis structures can be drawn for N2O:

(a) Using formal charges, which of these three resonance forms is likely to be the most important?
(b) The N-N bond length in N2O is 1.12 Ã…, slightly longer than a typical N == N bond; and the N-O bond length is 1.19 Ã…, slightly shorter than a typical N==N bond. (Table 8.5) Rationalize these observations in terms of the resonance structures shown previously and your conclusion for part (a).
