Which of the following forms micelles in aqueous solution above certain concentration?

Options

  1. ADodecyltrimethylammonium chloride
  2. BGlucose
  3. CUrea
  4. DPyridinium chloride

Correct answer

A. Dodecyltrimethylammonium chloride

Step-by-step solution

Surfactants detergents form micelles in aqueous solution above to their critical micelle concentration. Dodecyl trimethyl ammonium chloride is an example of cationic surfactant. Related Theory A micelle is an aggregate of surfactant molecules dispersed in a liquid, forming a colloidal suspension.
