Message:

When a molecule has resonance structure, does it mean there are delocalized
electrons in the molecule?
When will delocalization happen?
Can the resonance strcuture be replaced by a delocalized valence bond picture?
May you use N2O (nitrous oxide) as a example?
I've worked out the delocalized picture myself, but in my picture, the central
nitrogen has a lone pair, the molecule is not linear. it is worng.
My picture:
_______  <- delocalization of unpaired pi electrons from 2 atom
:N=N:-O::
":" means lone pair
Thanks for answering.
