Identify the macromolecular colloids from the list given below:
I. Synthetic rubber II. Rhombic sulphur III. Sodium stearate
IV. Cellulose V. Enzymes VI. Sodium lauryl sulphate
I. Synthetic rubber II. Rhombic sulphur III. Sodium stearate
IV. Cellulose V. Enzymes VI. Sodium lauryl sulphate
Show Hint
Macromolecular colloids are formed by polymers—both synthetic and natural (like rubber, enzymes, cellulose).

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Macromolecular colloids are those where macromolecules form the dispersed phase.
- Synthetic rubber (I): polymer → macromolecular colloid
- Cellulose (IV): natural polymer → macromolecular colloid
- Enzymes (V): biological macromolecules → macromolecular colloids
- Sodium stearate and sodium lauryl sulphate are associated colloids.
- Rhombic sulphur is not colloidal.
- Synthetic rubber (I): polymer → macromolecular colloid
- Cellulose (IV): natural polymer → macromolecular colloid
- Enzymes (V): biological macromolecules → macromolecular colloids
- Sodium stearate and sodium lauryl sulphate are associated colloids.
- Rhombic sulphur is not colloidal.
