The key thing is that you have to draw in the lone pair on nitrogen!
]]>I still dont get it. The second one with oxygen in example 3 i get, as after donation of the only lone pair, the lone pair is still shown. But in the case of nitrogen, i dont seem to see the mistake. Nitrogen DOES have a lone pair initially doesnt it?
]]>Aha, I figured it out. You DID answer it in the context afterward. Never mind. Thanks, Mi
]]>But, just wanna clarify on your Example 3, I think they are technically ok for these two. Why you still say CLOSE but not quite? Do the N and O assumingly have lone pairs in these two cases? Would you clarify it? Thanks a bunch!
]]>Aw shoot! A mistake on the “common mistakes” post. Thanks – fixed
]]>I just have a question about A though. Wouldn’t the resonance structure on the right have a positive charge on the bottom carbon?
]]>Oh snap. Thanks for the spot. Fixed!
]]>[Your answer to “C” is missing a charge in the right-hand structure.]
]]>Thanks for the spot! You’re right, need to fix this.
