| 21. | In addition, the alkene to alkane ratio increases.
|
| 22. | Alkane conformers arise from rotation around sp 3 hybridised carbon carbon sigma bonds.
|
| 23. | It is the substituent form of the alkane pentane.
|
| 24. | In this case an alkane is formed along with the formation of benzene.
|
| 25. | AFAIK this mixture will reduce aliphatic alcohols into alkanes.
|
| 26. | Partially fluorinated alkanes are the hydrofluorocarbons ( HFCs ).
|
| 27. | N-alkanes are also known to preserve detailed information of source material.
|
| 28. | Simple cycloalkanes have a prefix " cyclo-" to distinguish them from alkanes.
|
| 29. | Stronger intermolecular van der Waals forces give rise to greater boiling points of alkanes.
|
| 30. | In crude oil the alkane molecules have remained chemically unchanged for millions of years.
