All carboxylic acids contain the organic group(s)______ .

Question

Quizplus · Accepted Answer

Carboxylic acids all contain the −COOH group, which consists of a carbonyl group (−C=O) and a hydroxyl group (−OH) attached to the same carbon atom. Choices A and B are incorrect because they do not specify the presence of the carbonyl group, and choice C is incorrect because it does not specify the presence of a second group attached to the same carbon atom. Choice E is partially correct, but the −NH₂ group is not always present in carboxylic acids.
