Answer» Solution :(i) Anionic detergents Detergents in which the larger ion is an ANION are called anionic detergents. They are SALTS of sulphonic acid, e.g., `CH_(3)(CH_(2))_(10)CH_(2)SO_(3)^(-)N^(+)` . (ii) Cationic detergents : Detergents in which the larger ion is a cation are called cationic detergents. They are quaternary ammonium salts of LONG chain tertiary amines. For EXAMPLE, `[CH_(3)(CH_(2))_(15)N(CH_(3))_(3)]^(+)` (iii) Non-ionic detergents : Detergents which do not contain ions are called non-ionic detergents. For example, `CH_(3)(CH_(2))_(16)COO(CH_(2)CH_(2)O)nCH_(2)CH_(2)OH ` |
