Which of the following functional groups is characteristic of alcohols?
A
Carboxyl group (-COOH)
B
Carbonyl group (C=O)
C
Hydroxyl group (-OH)
D
Amino group (-NH2)
Verified step by step guidance
1
Identify the functional groups listed in the problem: Carboxyl group (-COOH), Carbonyl group (C=O), Hydroxyl group (-OH), and Amino group (-NH2).
Understand the structure and characteristics of each functional group: The Carboxyl group (-COOH) is found in carboxylic acids, the Carbonyl group (C=O) is found in aldehydes and ketones, the Hydroxyl group (-OH) is found in alcohols, and the Amino group (-NH2) is found in amines.
Recall the definition of an alcohol: Alcohols are organic compounds that contain one or more hydroxyl groups (-OH) attached to a carbon atom.
Match the definition of alcohols with the functional groups provided: The Hydroxyl group (-OH) is the characteristic functional group of alcohols.
Conclude that the functional group characteristic of alcohols is the Hydroxyl group (-OH).
