Multiple Choice
Which of the following functional groups is present in alcohols?
A
Carbonyl group (C=O)
B
Carboxyl group (-COOH)
C
Amino group (-NH2)
D
Hydroxyl group (-OH)
Verified step by step guidance
1
Begin by understanding what a functional group is: A functional group is a specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.
Identify the functional groups listed in the problem: Carbonyl group (C=O), Carboxyl group (-COOH), Amino group (-NH2), and Hydroxyl group (-OH).
Recall the structure of alcohols: Alcohols are organic compounds where a hydroxyl group (-OH) is bonded to a saturated carbon atom.
Compare the functional groups: Alcohols are characterized by the presence of the hydroxyl group (-OH), which is distinct from the other groups listed.
Conclude that the hydroxyl group (-OH) is the functional group present in alcohols, as it defines their chemical properties and reactions.
