(N/A) $(i)$ In multimolecular colloids,the colloidal particles are an aggregate of atoms or small molecules with a diameter of less than $1 \ nm$. The molecules in the aggregate are held together by van der Waal's forces of attraction. Examples include gold sol and sulphur sol.
$(ii)$ In macromolecular colloids,the colloidal particles are large molecules having colloidal dimensions. These particles have a high molecular mass. When these particles are dissolved in a liquid,a sol is obtained. Examples include starch,nylon,and cellulose.
$(iii)$ Associated colloids are substances that behave as normal electrolytes at low concentrations but form aggregated particles (micelles) at higher concentrations,thus behaving as colloidal solutions.
