The macromolecular colloids of the following are I. Starch solution II. Sulphur sol III. Synthetic detergent IV. Synthetic rubber

Options

  1. AI , II
  2. BII , III
  3. CIII , IV
  4. DI , IV

Correct answer

D. I , IV

Step-by-step solution

Macromolecules in suitable solvents form solutions in which the size of the macromolecules may be in the colloidal range. Such systems are called macromolecular colloids. These colloids are quite stable and resemble true solutions in many respects. Examples of naturally occurring macromolecules are starch, cellulose, proteins and enzymes; and those of man-made macromolecules are polythene, nylon, polystyrene, synthetic rubber, etc.
