Which is NOT an example of macro molecular colloid?
  1. Polythene
  2. Soap
  3. Nylon
  4. Proteins

Solution

Polythene: A synthetic polymer and an example of a macromolecule. It forms macromolecular colloids in certain conditions. Soap: Soap forms micelle-based colloids (associated colloids), not macromolecular colloids. Hence, it is NOT a macromolecular colloid. Nylon: A synthetic polymer with large molecular weight. It forms macromolecular colloids. Proteins: Naturally occurring macromolecules. They form macromolecular colloids. Final Answer: (2) Soap
