Now, what happens when you dehydrogenate an alcohol?

现在，对精进行脱氢会发生什么？

Not when an alcohol dehydrates you -- that would be a hangover -- but we dehydrogenate it.

不精使脱水——宿醉——而我们使它脱氢。

If you were paying attention, you learned that alcohols are organic compounds with hydroxyl groups, if you dehydrogenate them, the hydroxyl converts to a carbonyl and they become dehydrogenated alcohols or aldehydes.

如果留心的话，就会知道醇带有羟基的有机化合物， 如果它们脱氢， 羟基就会转化为羰基， 它们就会变成脱氢的醇或醛。
