Question:

Incomplete Lewis structures for the nitrous acid molecule, HNO2, and the nitrite ion, NO2-, are shown below.
(a) Complete each Lewis structure by adding electron pairs as needed.
(b) Is the formal charge on N the same or different in these two species?
(c) Would either HNO2 or NO2- be expected to exhibit resonance?
(d) Would you expect the N == O bond in HNO2 to be longer, shorter, or the same length as the N --- O bonds in NO2-? Explain.
Н-О—N—о 0-N=0
