Assertion : Molar entropy of vaporisation of water is different from ethanol. Reason : Water is more polar than ethanol.

Options

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

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion

Step-by-step solution

Molar entropy of vaporization of water is more than ethanol, as water has greater forces of attraction than ethanol.
