Assertion (A) The aggregate of carboxylate ions of fatty acids form a spherical shape. Reason (R) Soap helps in emulsification and washing away of oils.
  1. Both A and R are correct and R is the correct explanation of $A$.
  2. Both $\mathrm{A}$ and $\mathrm{R}$ are correct but $\mathrm{R}$ is not the correct explanation of $A$.
  3. $\mathrm{A}$ is correct but $\mathrm{R}$ is incorrect.
  4. $\mathrm{A}$ is incorrect but $\mathrm{R}$ is correct.

Solution

The aggregate of carboxylate ions of fatty acids forms a spherical shape known as micelle. Soap is emulsifier because it reduces surface tension and it can emulsify fats and oils by forming micelles around oil droplets. Hence, both A and R are correct but R is not the correct explanation of A.
