What happened was, the balloon took off, the butane gas has been cold overnight, and the burner was cutting out.

刚才气球起，过一夜，气的温度很低导致引擎熄火。

They're not structural isomers like n-butane and i-butane, instead, they're what we call cis-trans isomers.

它们不是像和那样的结构异构体，相反，它们就是我们所说的顺反异构体。

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， 异就是 2-甲基丙。

This is called normal butane or n-butane.

这称为或。

This is called isobutane or i-butane.

这称为异或异。

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， 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。

So the number of atoms is butane only allows for 2 isomers, n-butane and isobutane.

所以原子数是只允许2种异构体， 和异。

New York city police says a man was arrested after entering St. Patrick's cathedral with cans of gasoline, lighter fluid, and butane lighters.

纽约市警方说，一名男子携带汽油罐、打火机液体和打火机进入圣帕特里克大教堂被捕。

Things get more interesting, though, with the next alkane, butane, C4H10, because there are two different forms of it.

不过，对于下一个烃 C4H10， 事情变得更加有趣，因为它有两种不同的形式。

For example, n-butane boils at -0.5 degrees Celsius while isobutane boils at -11.7 degrees Celsius.

例如，的沸点为 -0. 5 摄氏度， 而异的沸点为 -11. 7 摄氏度。

And even though it has the same chemical formula as n-butane, its structure gives it different properties.

尽管它与具有相同的化学式， 但其结构赋予了它不同的特性。

Count up the carbons, 1-2-3 if you count that chain, 1-2-3-4 if you count this one so it's a butane derivative.

数一下碳，如果你数那条链， 则为 1-2-3， 如果数此链， 则为 1-2-3-4， 因此它是衍生物。

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， 它是的异构体，但根据所有重要的命名规则， 它实际上根本不是。

Though, since the second carbon is the only place where the methyl group can go without the molecule, once again becoming butane, properly proper chemists just drop the two and call it methylpropane.

虽然，由于第二个碳是甲基可以在没有分子的情况下离开的唯一位置，再次变成， 适当的化学家只是放弃这两个并称之为甲基丙。
