Multiple Choice
Which of the following is a functional group commonly found in alcohols?
A
Hydroxyl group (-OH)
B
Carbonyl group (C=O)
C
Carboxyl group (-COOH)
D
Amino group (-NH2)
Verified step by step guidance
1
Identify the functional groups listed in the problem: Hydroxyl group (-OH), Carbonyl group (C=O), Carboxyl group (-COOH), and Amino group (-NH2).
Recall the definition of an alcohol in organic chemistry: Alcohols are organic compounds where a hydroxyl group (-OH) is bonded to a carbon atom.
Understand that the hydroxyl group (-OH) is the characteristic functional group of alcohols, responsible for their chemical properties.
Compare the functional groups: The carbonyl group (C=O) is found in aldehydes and ketones, the carboxyl group (-COOH) is found in carboxylic acids, and the amino group (-NH2) is found in amines.
Conclude that the hydroxyl group (-OH) is the functional group commonly found in alcohols, distinguishing them from other organic compounds.
