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

Answer»

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