Now, what happens when you dehydrogenate an alcohol?

现在，当对酒精进行脱氢生什么？

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

不是当酒精脱水——那将是宿醉——而是我脱氢。

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，就知道醇是带有羟基的有机化合物， 如果将脱氢， 羟基就转化为羰基， 就变成脱氢的醇或醛。
