Vedclass · Answer

(B) surfactant (surface active agent) is a molecule that has both a hydrophobic tail and a hydrophilic head,which allows it to reduce surface tension. $A$ is cetyltrimethylammonium bromide,a cationic surfactant. $C$ is sodium stearyl sulfate,an anionic surfactant. $D$ is sodium palmitate,an anionic surfactant. $B$ is $CH_3-(CH_2)_{14}-CH_2-NH_2$ (hexadecylamine),which is a long-chain primary amine. It does not possess an ionic or highly polar head group capable of forming a stable micelle in water at neutral pH,and thus is not considered a typical surfactant.
