Which from following is classified as multimolecular colloid?

Options

  1. AStarch
  2. BCellulose
  3. CS ₈ sulphur molecules
  4. DPlastics

Correct answer

C. S ₈ sulphur molecules

Step-by-step solution

Multimolecular colloids result from the aggregation of numerous small molecules or atoms into colloidal-sized particles. Individual components possess diameters below 1 nm, while the aggregated particles fall within the 1–1000 nm colloidal range. Evaluating the options: starch and cellulose are macromolecular colloids composed of large polymer molecules intrinsically at colloidal scale. Plastics similarly constitute macromolecular colloidal systems. S₈ sulfur molecules demonstrate distinct behavior. When dissolved
