Hi,
Would someone be able to explain why you end up with positive charges on the resonance structures of nitrobenzene? I thought that if the carbon went from being part of a double bond to being part of a single bond, then it would have a negative charge.
Many thanks![]()

The number of electrons = the non-bonding electrons + (bonding pairs)/2
If both of the electrons from a bond go somewhere else the (previously neutral) atom loses a one half share of a bonding pair = 1 electron and so develops a positive charge.
Look at your example in the attachment and count up the electrons and protons at each atom (not forgetting inner shell electrons)
