Solution

The difference between multimolecular and macromolecular colloids is shown:
Multimolecular colloidsMacromolecular colloids
The colloidal particles are aggregates of a large number of atoms or molecules having a diameter of less than 1 nm.
The colloidal particles are macromolecules having a very large molecular mass.
Weak van der Waals forces are present between particles.
Strong chemical bonds are present between macromolecular particles.

Sulphur sol is a multimolecular colloid and contains S8 molecules while starch is a macromolecular colloid.
Associated colloids (soaps and detergents) behave as normal electrolytes at low concentrations and show colloidal properties at high concentrations due to the formation of aggregated particles called micelles.
