Which of the following forms cationic micelles above certain concentration?
Which of the following forms cationic micelles above certain concentration?
- A. Sodium acetate
- B. Urea
- C. cetyl trimethylammonium chloride
- D. Sodium dodecyl sulphonate
Step-by-step solution
Cetyl trimethylammonium chloride is a cationic surfactant that forms cationic micelles above its critical micelle concentration. Sodium acetate is a salt, urea is a non-ionic compound, and sodium dodecyl sulphonate is an anionic surfactant, so they do not form cationic micelles.
