Carboxylic Acids
羧酸
Carboxylic acids are hydrocarbon derivatives for which the functional group is the carboxyl group
羧酸是烃的衍生物，其功能基团为羧基
The R in the general form is typically an alkyl group. The simplest of the carboxylic acids is formic acid, where the R in the above general form is just hydrogen. Formic acid is a constituent of bee stings and the bites of other insects including mosquitos. When formic acid was discovered in space in some of the interstellar dust clouds, it generated a lot of bad jokes about cosmic mosquitos. Acetic acid is the next step up in complexity, with R being a methyl group. Vinegar contains about 5% acetic acid. These two carboxylic acids have the forms:
一般形式中的R通常是一个烷基集团。最简单的羧酸是甲酸，其中上述一般形式中的R仅仅是氢。甲酸是蜂 sting 和其他昆虫（包括蚊子）叮咬的成分。当甲酸在一些星际尘埃云中被发现时，引发了关于宇宙蚊子的许多恶作剧。接下来的复杂度是乙酸，其中R是一个甲基。醋中含有约5%的乙酸。这两种羧酸的形式如下：
Carboxylic acids are important intermediate products for the production of esters and amides.
羧酸是生产酯和酰胺的重要中间产物。
