| 单词 | alkane |
| 例句 | Because of the sp3 hybridization, the bond angles in carbon chains are close to 109.5°, giving such chains in an alkane a zigzag shape. Chemistry 2019-02-14T00:00:00Z Light alkane oxidation using catalysts prepared by chemical vapour impregnation: tuning alcohol selectivity through catalyst pre-treatment. Mild oxidation of methane to methanol or acetic acid on supported isolated rhodium catalysts 2017-11-28T05:00:00Z The double bonds create a weak link in the short alkane chains—a vulnerability that the second catalyst exploits to split the alkane chain. Catalysts could turn trash bags into fuel 2016-06-17T04:00:00Z It generates long alkane chains that are the immediate precursors to diesel fuel. Is "All of the Above" the Right Strategy for U.S. Energy? A Q&A with Steven Chu 2012-03-12T11:15:00.203Z Melt these together over a slow fire, mixing with them a little powder of alkane root to color it.

Chemistry 2019-02-14T00:00:00Z For example, halogens add to the double bond in an alkene instead of replacing hydrogen, as occurs in an alkane: Chemistry 2019-02-14T00:00:00Z This molecule is now a substituted alkane and will be named as such. Chemistry 2019-02-14T00:00:00Z The main source of these liquid alkane fuels is crude oil, a complex mixture that is separated by fractional distillation. Chemistry 2019-02-14T00:00:00Z The name of an alkyl group is obtained by dropping the suffix -ane of the alkane name and adding -yl: Chemistry 2019-02-14T00:00:00Z The name of an alkene is derived from the name of the alkane with the same number of carbon atoms. Chemistry 2019-02-14T00:00:00Z Each of the carbon atoms in an alkane has sp3 hybrid orbitals and is bonded to four other atoms, each of which is either carbon or hydrogen. Chemistry 2019-02-14T00:00:00Z We call a substituent that contains one less hydrogen than the corresponding alkane an alkyl group. Chemistry 2019-02-14T00:00:00Z |
