Vedclass · Answer

(D) Cationic detergents are quaternary ammonium salts of amines with acetates,chlorides,or bromides as anions. They consist of a long hydrocarbon chain attached to a nitrogen atom,which carries a positive charge. Because of this structure,the cationic part is the active site,which gives them germicidal properties. They are relatively expensive compared to anionic detergents and are not used as common household detergents. An example is $CH_3(CH_2)_{15}N^+(CH_3)_3Br^-$,known as cetyltrimethylammonium bromide.

Which one of the following statements is "not correct" about cationic detergents?
