| By careful use of appropriate conditions and catalysts alkanes can be converted into other hydrocarbons such as the alkenes and alkynes. |
| Furthermore, there was no evidence of ethyl esters, dimers, alkanes or alkenes, which might be expected for an oxidative reaction. |
| The samples showed high concentrations of methane, ethane, butane, and propane, gases in a class of hydrocarbons called alkanes. |
| In discussing the alkanes as a functional group, the terms aliphatic and alicyclic are used. |
| The ethyl group is found for example during the thermal degradation of alkanes as is encountered during various petrochemical processes. |
| The cycloalkanes are saturated hydrocarbons like the alkanes, but form rings with two hydrogen atoms per carbon. |
