At the critical micelle concentration (CMC), the surfactant molecules :
Open in App
Solution
The correct option is B associate
Micelles form by the cooperative binding of monomers to one another at concentrations exceeding a rather narrow region called the critical micellization concentration (CMC). The latter is the concentration of a surfactant at which a large number of micelles form in its solution that have been in thermodynamic equilibrium with the molecules (ions), and a number of properties of the solution sharply change.
This sharp transition to the CMC region for systems with flexible chains could be attributed to the cooperative nature of the self- association process. This makes aggregates containing many monomers considerably more stable than small particles. The CMC has been one of the most easily determined experimentally and useful quantitative characteristics of solutions of surfactants with flexible chains.
