The most unlikely representation of resonance structure of p-nitrophen

1.	The most unlikely representation of resonance structure of p-nitrophenoxide is
Answer» Solution :NITROGEN in option (c) has two double bonds and one single BOND. THEREFORE, it has `10 (2 XX 4 + 1 xx 2)` electrons in the valence shell. This is against octet rule and HENCE resonance structure (c) is most unlikely.
