In the one that minimizes the formal charge, how many double bonds does the chlorine atom make? How many double bonds does each N2O5 resonance structures have. Draw the dominant Lewis structure for NO2+. Note, that this ion is isoelectronic with CO2. How many double bonds does this resonance structures have.
why a bromine radical is more selective than a chlorine radical during abstraction of a hydrogen on a hydrocarbon?
