Which of the following is an anionic synthetic detergent?

  1. APolyethylene glycol stearate
  2. BGlyceryl tristearate
  3. CCetyltrimethylammonium bromide
  4. DSodium dodecylbenzenesulphonate

Answer: D

In sodium dodecylbenzenesulphonate the surface-active part is the sulphonate anion , so it is anionic. Cetyltrimethylammonium bromide is cationic, polyethylene glycol stearate is non-ionic and glyceryl tristearate is a neutral fat, not a detergent.
