Which of the following is NOT a resonance structure of the amide bond shown below?

Question

Quizplus · Accepted Answer

The correct resonance structure should maintain a double bond between the carbon and oxygen atoms while also maintaining a lone pair of electrons on the nitrogen atom. Option D does not have a double bond between the carbon and oxygen atoms, making it an incorrect resonance structure. The other options all maintain a double bond between the carbon and oxygen atoms and a lone pair of electrons on the nitrogen atom, so they are all possible resonance structures.
