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.
- A Both A and R are correct and R is the correct explanation of \(A\).
- B Both \(\mathrm{A}\) and \(\mathrm{R}\) are correct but \(\mathrm{R}\) is not the correct explanation of \(A\).
- C \(\mathrm{A}\) is correct but \(\mathrm{R}\) is incorrect.
- D \(\mathrm{A}\) is incorrect but \(\mathrm{R}\) is correct.
Answer & Solution
Correct Answer
(B) Both \(\mathrm{A}\) and \(\mathrm{R}\) are correct but \(\mathrm{R}\) is not the correct explanation of \(A\).
Step-by-step Solution
Detailed explanation
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…
