| 11. | Where are we going to get all of our hydrocarbons from, especially ethene, the most commercial produced organic compound?
|
| 12. | This method, however, is expensive and inefficient, so the addition polymer of ethene ( polyethylene ) is generally used.
|
| 13. | In addition to benzene, acetylene and ethene, pyridine also decomposes on ruthenium surfaces, leaving bound fragments on the surface.
|
| 14. | The refinery, called Basic Petrochemical Unit, will use Brazilian crude oil to make ethene and propene, used to produce plastics.
|
| 15. | The structure is isoelectronic with C 2 H 6 2 +, which would arise from the diprotonation of the planar molecule ethene.
|
| 16. | Since this is a [ 4 + 2 ], the reaction can be simplified by considering the reaction between butadiene and ethene.
|
| 17. | The HOMO of butadiene and the LUMO of ethene are both antisymmetric ( rotationally symmetric ), meaning the reaction is allowed .*
|
| 18. | :: Ethene and fermentation are articles of particular interest . ~ U ) 03 : 11, 7 March 2011 ( UTC)
|
| 19. | Upon heating to 150-190 �C decomposition occurs with the formation of tetrakis ( dimethylamino ) ethene, a strong electron donor.
|
| 20. | Classified as a diarylethene, it features a central ethene double bond substituted with phenyl groups on each carbon atoms of the double bond.
