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.

Options

  1. ABoth A and R are correct and R is the correct explanation of A .
  2. BBoth A and R are correct but R is not the correct explanation of A .
  3. CA is correct but R is incorrect.
  4. DA is incorrect but R is correct.

Correct answer

B. Both A and R are correct but R is not the correct explanation of A .

Step-by-step 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.
