原声例句
Crash Course 综合篇 If we wanted to give a technical name for it, isobutane would be 2-methylpropane. 如果我们想给它一个技术名称, 异丁烷就是 2-甲基丙烷。 Crash Course 综合篇 This is called isobutane or i-butane. 这称为异丁烷或异丁烷。 Crash Course 综合篇 For example, n-butane boils at -0.5 degrees Celsius while isobutane boils at -11.7 degrees Celsius. 例如,正丁烷的沸点为 -0. 5 摄氏度, 而异丁烷的沸点为 -11. 7 摄氏度。 Crash Course 综合篇 Earlier, I introduced you to isobutane, a compound with four carbons that are not all in a chain. 早些时候,我向您介绍了异丁烷, 这是一种具有四个碳原子的化合物, 这些碳原子并不全部位于链中。 Crash Course 综合篇 So the number of atoms is butane only allows for 2 isomers, n-butane and isobutane. 所以原子数是丁烷只允许2种异构体, 正丁烷和异丁烷。 Crash Course 综合篇 They call that isobutane and it is an isomer of butane, but according to these all important rules of nomenclature, it's not actually any sort of butane at all. 他们称其为异丁烷, 它是丁烷的异构体,但根据所有重要的命名规则, 它实际上根本不是丁烷。 |
