Vedclass · Answer

(D) 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.Examples of man-made macromolecules are polythene,nylon,polystyrene,synthetic rubber,etc.Therefore,$I$ (Starch solution) and $IV$ (Synthetic rubber) are examples of macromolecular colloids.$II$ (Sulphur sol) is a multimolecular colloid,and $III$ (Synthetic detergent) is an associated colloid (micelle).

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