Vedclass · Accepted Answer

Cetyltrimethylammonium bromide

Vedclass · Answer

(B) cationic micelle is formed by surfactants that have a positively charged head group in an aqueous solution. $Cetyltrimethylammonium \ bromide$ $(CH_3(CH_2)_{15}N(CH_3)_3^+Br^-)$ dissociates in water to give a long-chain cation $(CH_3(CH_2)_{15}N(CH_3)_3^+)$,which forms cationic micelles. $Sodium \ dodecyl \ sulphate$ and $Sodium \ stearate$ form anionic micelles because they contain negatively charged head groups ($SO_4^-$ and $COO^-$ respectively). $Urea$ is a non-ionic solute and does not form micelles.
