Which of the following forms cationic micelles above certain concentration?

Options

  1. ASodium dodecyl sulphate
  2. BSodium acetate
  3. CUrea
  4. DCetyltrimethylammonium bromide

Correct answer

D. Cetyltrimethylammonium bromide

Step-by-step solution

Colloids which behave as normal electrolytes at low concentration, but exhibit colloidal properties at higher concentration due to the formation of aggregated particles called micelles. The micelles are formed by the association of dispersed particles above a certain concentration which is known as CMC. From the above compounds only Cetyltrimethyl ammonium bromide forms cationic micelles.
