Cetyltrimethylammonium bromide

Vedclass · Answer

(B) Cationic micelles are formed by surfactants where the long-chain cation is the active part. $Cetyltrimethylammonium \ bromide$ $(CH_3(CH_2)_{15}N(CH_3)_3^+Br^-)$ dissociates in water to give a long-chain cation,which aggregates to form cationic micelles. $Sodium \ dodecyl \ sulphate$ and $Sodium \ acetate$ form anionic micelles because the long-chain part is an anion. $Urea$ does not form micelles.
