Now, what happens when you dehydrogenate an alcohol?

现在，当对酒精进行脱氢时会发生什？

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

不是当酒精使脱水时——那将是——是我们使它脱氢。

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，就会知道醇是带有羟基的有机合物， 如果将它们脱氢， 羟基就会转为羰基， 它们就会变成脱氢的醇或醛。
