Sodium stearate CH3(CH2)16COO−Na+{CH}_{3}{\left({CH}_{2}\right)}_{16}{COO}^{-}{Na}^{+} is an anionic surfactant which forms micelles in oil. Choose the correct statement for it from the following :

Options

  1. AIt forms spherical micelles with CH3(CH2)16−{CH}_{3}{\left({CH}_{2}\right)}_{16} - group pointing towards the centre of sphere.
  2. BIt forms non-spherical micelles with −COO−- {COO}^{-} group pointing outwards on the surface.
  3. CIt forms spherical micelles with CH3(CH2)16−{CH}_{3}{\left({CH}_{2}\right)}_{16} - group pointing outwards on the surface of sphere
  4. DIt forms non-spherical micelles with {CH}_{3}{\left({CH}_{2}\right)}_{16} -group pointing towards the centre.

Correct answer

A. It forms spherical micelles with CH3(CH2)16−{CH}_{3}{\left({CH}_{2}\right)}_{16} - group pointing towards the centre of sphere.

Step-by-step solution

Forms spherical micelles with CH3(CH2)16{CH}_{3}{\left({CH}_{2}\right)}_{16} group pointing towards the centre of sphere
