Which from following is an example of multimolecular colloid?
Which from following is an example of multimolecular colloid?
Updated On: Feb 9, 2024
- Cellulose
- Plastic
- S8 molecule
- Starch
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Starch is a complex carbohydrate consisting of numerous glucose units bonded together. In a colloidal suspension, starch particles aggregate and form a colloidal system. The dispersed phase in this case consists of multiple starch molecules, making it a multimolecular colloid.
Therefore, the correct option is (D) Starch

Concepts Used:
Classification of Colloids
Based on the Nature of Interaction Between Dispersed Phase and Dispersion Medium:
- Hydrophilic colloids: These are water-loving colloids. The colloid particles are attracted to the water. They are also known as reversible sols. Examples include Agar, gelatin, pectin, etc
- Hydrophobic colloids: These are the opposite in nature to hydrophilic colloids. The colloid particles are repelled by water. They are also called irreversible sols. Examples include Gold sols, clay particles, etc
Based on Type of Particles of Dispersed Phase:
- Multimolecular Colloids: A large number of smaller molecules of a substance add on together on mixing and form species that are in the colloidal range.
- Macromolecular Colloids: In this colloid, the macromolecule forms a solution with a solvent. The size of particles remains in the range of colloidal particle size. Here, the colloidal particles are macromolecules having a very large molecular mass.
- Associated Colloids: Few substances react as strong electrolytes when they are in low concentration, but act as colloidal sols when they are in high concentration. In high concentration, particles aggregate and show colloidal behaviour and these particles are known as the micelles. They are also known as associated colloids. The formation of micelles occurs above a certain temperature and specific concentration. These colloids can be reverted by diluting it.
