| 1. | Alkanes are only weakly reactive with ionic and other polar substances.
|
| 2. | Alkanes have also been detected in meteorites such as carbonaceous chondrites.
|
| 3. | Alkyl substituted derivative are particularly soluble, even in alkane solvents.
|
| 4. | Cycloalkanes have similar properties to alkanes but have higher boiling points.
|
| 5. | Alkanes of 6 to 22 carbons have been observed as substrates.
|
| 6. | Alkanes are not very reactive and have little biological activity.
|
| 7. | For a more complete list, see List of alkanes.
|
| 8. | From pentane to octane the alkanes are highly volatile liquids.
|
| 9. | Linear alkanes were removed in favor of highly branched and cyclic molecules.
|
| 10. | Lithium aluminium hydride also reduces alkyl halides to alkanes,.
