| 1. | Isocyanides are best shown as a mixture of both resonance structures.
|
| 2. | In resonance structures, major and minor contributing structures may exist.
|
| 3. | Both the regioselectivity and the resonance structures and the inductive effect.
|
| 4. | In this case, there are three possible resonance structures.
|
| 5. | One explanation relies on the carbocation resonance structure of the Criegee intermediate.
|
| 6. | The cyanide group can also stabilize anions by delocalizing negative resonance structures.
|
| 7. | If two resonance structure are exactly equivalent, for example:
|
| 8. | The true structure lies somewhere between these resonance structures.
|
| 9. | This yields the conjugate base ( stabilized by resonance structures ) and thiocyanic acid.
|
| 10. | This difference, established by X-ray diffraction, is consistent with the resonance structures.
