Question

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

• A. I, III \& VI only
• B. II, III \& IV only
• C. III, IV \& V only
• D. I, IV \& V only

Hint:

Macromolecular colloids are formed by polymers—both synthetic and natural (like rubber, enzymes, cellulose).

Answer 1

The Correct Option is D

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.
