choose the resonance structure that results from the arrow pushing scheme below:
Answer
Explanation:
Step1: Analyze arrow - pushing
The curved arrow from the lone - pair on nitrogen moves towards the carbon - nitrogen bond, and the curved arrow from the carbon - oxygen π - bond moves onto the oxygen atom.
Step2: Determine charge distribution
When the lone - pair on nitrogen forms a π - bond with carbon, nitrogen gains a positive charge. When the π - bond between carbon and oxygen breaks and the electrons move to oxygen, oxygen gains a negative charge.
Answer:
The third structure (where nitrogen has a positive charge and oxygen has a negative charge)
