Q80 / 180 · AIIMS 2003 · Chemistry
Which one of the following is not a surfactant?
- A
- Correct answerB$\mathrm{CH}_3-\left(\mathrm{CH}_2\right)_{14}-\mathrm{CH}_2-\mathrm{NH}_2$
- C$\mathrm{CH}_3-\left(\mathrm{CH}_2\right)_{16}-\mathrm{CH}_2 \mathrm{OSO}_2^{-} \mathrm{Na}^{+}$
- D$\mathrm{OHC}-\left(\mathrm{CH}_2\right)_{14}-\mathrm{CH}_2-\mathrm{COO}^{-} \mathrm{Na}^{+}$
Solution
To act as surfactant, there should be both polar and non-polar ends in the molecules.
Hence, the correct answer is option: 'B'.
