Assertion : The micelle formed by sodium stearate in water has - COO ⁻ groups at the surface. Reason : Surface tension of water is reduced by the addition of stearate.

Options

  1. AIf both assertion and reason are true and the reason is the correct explanation of the assertion
  2. BIf both assertion and reason are true and the reason is not the correct explanation of the assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer
