| 1. | The carbanions generated by deprotonation of terminal alkynes are called acetylides.
|
| 2. | Specialty alkynes are prepared by dehydrohalogenation of dihalides or vinyl halides.
|
| 3. | In some cases where alkynes are present, phenols sometimes form:
|
| 4. | Angles for nucleophilic attack on alkynes were reviewed and redefined recently.
|
| 5. | Would an alkyne proton be a sharp peak in proton NMR?
|
| 6. | Vinyl silyl can be made from terminal alkyne or other methods.
|
| 7. | As an alkyne, acetylene is bonded together in a triple bond.
|
| 8. | Alkynes occur in some pharmaceuticals, including the contraceptive noretynodrel.
|
| 9. | Alkynes are reduced only if an alcohol group is nearby.
|
| 10. | In alkene radicals proton abstraction to an alkyne is preferred.
