Multiple Choice
Which of the following is a characteristic functional group of alcohols?
A
Hydroxyl group (-OH)
B
Amino group (-NH2)
C
Carboxyl group (-COOH)
D
Carbonyl group (C=O)
Verified step by step guidance
1
Identify the functional groups listed in the options: Hydroxyl group (-OH), Amino group (-NH2), Carboxyl group (-COOH), and Carbonyl group (C=O).
Recall the definition of a functional group: a specific group of atoms within a molecule that is responsible for a characteristic chemical reaction of that molecule.
Understand that alcohols are organic compounds characterized by the presence of a hydroxyl group (-OH) attached to a carbon atom.
Compare the functional groups: The hydroxyl group (-OH) is specifically associated with alcohols, whereas the amino group (-NH2) is associated with amines, the carboxyl group (-COOH) with carboxylic acids, and the carbonyl group (C=O) with ketones and aldehydes.
Conclude that the characteristic functional group of alcohols is the hydroxyl group (-OH).
