Title: Why dosen't No2 form according to the octet rule?
Post by: vicentemartinez on March 29, 2020, 12:17:55 PM

Supposedly every atom that is in the second period of the periodic table has to obey the octet rule, this means that they have to be surrounded by 8 electrons (or so I was taught). Studying resonance in an exercise they showed how nitrogen as NO2 can form 5 bonds, which would mean that NO2 does not behave according to the rule previously mentioned. I am at a loss, any help would be great.

Nitrogen can form several compounds with oxygen, N₂O, NO, N₂O₃, NO₂, N₂O₄ and N₂O₅.
Not all compounds following the 8 electrons law.

@OP, Can you show us the resonance forms that you mean?
