Q1. To which family of organic compounds do the following compounds belong? Explain.

Background

Topic: Functional Groups in Organic Chemistry

This question tests your ability to recognize and classify organic compounds based on their structural formulas. Understanding functional groups is essential in biochemistry, as they determine the chemical properties and reactivity of molecules.

Key Terms and Concepts:

• Hydrocarbon: Compound containing only carbon and hydrogen.

• Alkene: Hydrocarbon with at least one carbon-carbon double bond.

• Alcohol: Compound with an –OH (hydroxyl) group attached to a carbon.

• Aromatic Hydrocarbon: Compound with a ring structure and alternating double bonds (e.g., benzene).

• Ketone: Compound with a carbonyl group (C=O) bonded to two carbons.

• Amide: Compound with a carbonyl group (C=O) bonded to a nitrogen (–NH2).

• Amine: Compound with a nitrogen atom bonded to carbon(s) and/or hydrogen(s).

• Disulfide: Compound containing an S–S bond.

Step-by-Step Guidance

1. Examine each compound for the elements present (carbon, hydrogen, oxygen, nitrogen, sulfur).

2. Identify any multiple bonds (double or triple bonds) or ring structures in the molecule.

3. Look for characteristic functional groups, such as –OH (alcohol), C=O (carbonyl), –NH2 (amine), or S–S (disulfide).

4. Determine if the compound belongs to more than one family (e.g., a molecule with both an amide and an amine group).

5. Use a functional group table or your knowledge to classify each compound based on the features you identified.
