| 11. | Catalyzed hydroboration-oxidation of substituted alkenes can be rendered enantioselective.
|
| 12. | Many higher alcohols are produced by hydroformylation of alkenes followed by hydrogenation.
|
| 13. | More useful is the E1 elimination reaction of alcohols to produce alkenes.
|
| 14. | Lithium aluminium hydride does not reduce simple alkenes or arenes.
|
| 15. | One way to observe this distortion is in pyramidal alkenes.
|
| 16. | The compound is widely used as a catalyst for hydrogenation of alkenes.
|
| 17. | In alkene radicals proton abstraction to an alkyne is preferred.
|
| 18. | Difluoroalkenes are alkenes that have two fluorines on their sp 2 carbon.
|
| 19. | Generally, the alkenes are known to react with electrophiles.
|
| 20. | Alkenes can also be oxidised and cleaved in the Lemieux Johnson oxidation.
