Read each question carefully and provide the best answer. This worksheet will test your knowledge of common functional groups in organic chemistry.
1. The functional group containing an -OH group attached to a carbon atom is called a .
2. A group is characterized by a carbon atom double-bonded to an oxygen atom.
3. The functional group found in carboxylic acids, represented as -COOH, is the group.
4. Amines contain a functional group, which includes a nitrogen atom bonded to hydrogen and/or carbon atoms.
5. Which of the following functional groups is found in ketones and aldehydes?
Hydroxyl
Carboxyl
Carbonyl
Amino
6. Draw the general structure of an ester functional group. Label the key atoms.
7. Alcohols contain a carbonyl functional group.
True
False
Match each functional group with its correct description.
8. Ether
a. Contains a nitrogen atom bonded to at least one hydrogen or carbon atom.
9. Amine
b. Contains an oxygen atom bonded to two carbon atoms.
10. Carboxylic Acid
c. Contains a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group.
