Lewis dot structures of complex molecules

Click For Summary
SUMMARY

The discussion focuses on determining the Lewis dot structures for two complex molecules involving carbon, nitrogen, and oxygen. The first molecule features a carbon-nitrogen double bond and a carbon-oxygen single bond, while the second molecule includes a carbon-nitrogen double bond and a carbon-oxygen double bond. Key issues raised include the potential charges on oxygen and nitrogen due to their bonding configurations, emphasizing the importance of adhering to neutral species in the assignment.

I am not at all sure this is correct and the software that accepts answers for my school agrees with that assesment, any assistance will be greatly appreciated

Your first answer has a single bond between the carbon and the oxygen. That oxygen also has six other electrons around it. Would that result in the oxygen having a charge? You also show the enamine (with friends like that, who needs enamines?) nitrogen having four bonds to it. What would the charge be for that? Does your assignment want you to postulate neutral species? I'm betting it does.
