Question

Cationic surfactants is/are:

• A. $C_{17}{H}_{35}COONa$
• B. $C_{17}{H}_{35}COOK$
• C. $C_{17}{H}_{35}S{O}_{3}Na$
• D. $C_{16}{H}_{33}N(C{H}_3{)}_{3}Cl$

Answer 1

The correct option is D $C_{16}{H}_{33}N(C{H}_3{)}_{3}Cl$

Cationic surfactant is $C_{16}{H}_{33}N(C{H}_3{)}_{3}Cl$. In this, the larger part (hydrocarbon) of the molecule is cation $C_{16}{H}_{33}N(C{H}_3{)}_3^{+}$ .
