Question
Which "resonance structure" (b or c) does not contribute to the molecule $\mathrm{CH}_{3} \mathrm{NOC} \mathrm{C}_{2}$ (a)? Why doesn't it contribute?
Step 1
This structure is less stable because oxygen is more electronegative than nitrogen, so it is less likely to carry a positive charge. Structure c) has a positive charge on the nitrogen atom and a negative charge on the carbon atom. This structure is more stable Show more…
