Which of the following is NOT an example of synthetic detergent?

Options

A
B ${CH}_{3} - {\left({CH}_{2}\right)}_{16} - {COO}^{-}{Na}^{+}$
C
D ${CH}_{3}{\left({CH}_{2}\right)}_{16}COO{\left({CH}_{2}{CH}_{2}O\right)}_{n}{CH}_{2}{CH}_{2}OH$

Correct answer

B. ${CH}_{3} - {\left({CH}_{2}\right)}_{16} - {COO}^{-}{Na}^{+}$

Step-by-step solution

Sulphonates and quaternary ammonium salt of long chain fatty acids are used as synthetic detergents.

option $\left(2\right) {CH}_{3} - {\left({CH}_{2}\right)}_{16} - {COO}^{-}{Na}^{+}$ is just a hydrocarbon chain which is insoluble in water.Hence, it is not a synthetic detergent.
