Root Explanation

Carboxylic is formed from "carboxyl" (from the combination of "carbo-" meaning carbon and "-yl" indicating a functional group) and the suffix "-ic" (meaning pertaining to). The term refers to compounds that contain a carboxyl group, which is a functional group consisting of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group.

Memory Tip

Think of 'carbon' ('carbo-') being part of a special group ('-yl') that is 'pertaining to' ('-ic') certain compounds. This helps you remember that carboxylic relates to compounds containing a carboxyl group.
