What are cationic detergents? Give an example

Explanation:

Cationic detergents are quaternary ammonium salts of amines and have chlorides (Cl^-), bromides(Br^-)or acetates(CH₃COO^-) as the anionic part. The cationic component of these detergents consists of a long hydrocarbon chain with the N atom of ammonium salt bearing a positive charge since it forms four bonds i.e. quaternary in nature.

An example of cationic detergent is: Cetyltrimethylammonium bromide which is commonly used in hair conditioners.

Final Answer:

Hence, cationic detergents are quaternary ammonium salts of amines having Br^-, Cl^- or CH₃COO^- as anionic part.

Example: Cetyltrimethylammonium bromide.
