Question

Quizplus · Accepted Answer

The carboxylic acid functional group is composed of a carbonyl group (C=O) and a hydroxyl group (-OH) bonded to the same carbon atom. It is commonly referred to as the carboxyl group (-COOH). Therefore, the correct choice is B - carboxyl group. A is incorrect because a carbonyl group refers only to the C=O portion of the carboxyl group. C is incorrect because a carboxylate group is the deprotonated form of a carboxylic acid (-COO-), which is missing the acidic hydrogen ion. D is incorrect because there is no such thing as a carbohydroxyl group.
