If they've got a double bond, we call them alkenes, and those with triple bonds are alkynes.

们有双键，我们称们为烯烃，而那些有三键是炔烃。

In essence, the azide and the alkyne are like the two halves of a snap-together buckle.

从本质上讲，叠氮化物和炔烃就像一个扣在一起两半。

Thus, no isomers with alkynes. Phew. OK I'm done describing for the moment.

因此，与炔烃没有异构体。呸。好，我暂时完成描述。

They can be alkanes or alkenes, sometimes, even rarely, alkynes.

们可以是烷烃或烯烃，有时至很少是炔烃。

All the other naming rules apply to alkenes and alkynes too.

所有其他命名规则也适用于烯烃和炔烃。

There's only one letter changing here: A in alkanes changes to E for alkenes and then to Y for alkynes.

这里只有一个字母发生变化：烷烃中 A 变为烯烃中 E，然后变为炔烃中 Y。

Alkenes can be made into alkanes and alkynes can become either alkenes or alkanes depending on how many atoms are added.

烯烃可以变成烷烃，炔烃可以变成烯烃或烷烃，具体取决于添加数。

The triple bonds in alkynes, meanwhile, are composed of 1 sigma bond and 2 pi bonds for a total of 3 bonds.

同时，炔烃中三键由 1 个 sigma 键和 2 个 pi 键组成，总共 3 个键。

Copper ions are frequently poisonous to biological systems.So Dr Bertozzi decided to work on a way to make azides and alkynes react without their involvement.

铜离通常对生物系统有毒。因此，Bertozzi 博士决定研究一种方法，使叠氮化物和炔烃在没有们参与情况下发生反应。

You also learned a little bit about cis-trans isomerism and learned a few important reactions of alkenes and alkynes such as hydrogenation, halogenation, and polymerization.

您还了解了一些顺反异构现象，并了解了烯烃和炔烃一些重要反应，例氢化、卤化和聚合。

Her solution, which she published in 2004, was to include the alkyne half of the buckle in a molecule that would put it under strain and thus make it more reactive.

她于 2004 年发表解决方案是将带扣炔烃一半包含在一个分中，使其处于应变状态，从而使其更具反应性。

So three words representing three different groups of organic compounds: alkanes for all single bonds, alkenes if they contain double bonds, and alkynes if they contain one or more triple bonds.

所以三个词代表三组不同有机化合物：所有单键烷烃，含有双键烯烃，含有一个或多个三键炔烃。

That may not sound like a big deal at first, but alkenes and alkynes don't have that kind of freedom, and that simple fact has a huge affect on their properties.

乍一听这可能没什么大不了，但烯烃和炔烃没有那种自由度， 而这个简单事实对们性质有巨大影响。

If you paid attention, you learned that hydrocarbons with double bonds are called alkenes and those with triple bonds are called alkynes and that the naming rules are the same as for alkanes.

你注意话，你会发现带有双键碳氢化合物称为烯烃， 带有三键碳氢化合物称为炔烃， 并且命名规则与烷烃相同。
