3.45 quick question

Postby Faisal Alshamaa - 1L » Wed May 23, 2018 11:16 pm

Draw the Lewis structures that contribute to the resonance hybrid of nitryl chloride, ClNO2 (N is the central atom).

Hello, I get this problem but I was just wondering why N is the central atom instead of Cl, when N has a higher electronegativity than Cl (FONCl).

Thanks!

nitrogen has a lower electronegativity since it's closer to the left (or further away from fluorine), so it goes in the center

I see the point. But N has one fewer full shell than Cl which contributes to its electronegativity. I think it’s more understandable to say that N has fewer valence electrons and thus more bonding opportunities than Cl without breaking the octet rule. Also NO2 is like pretty common combination.

N has less valence electrons than Cl and is more willing to give up its electrons than Cl.
