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

A

and (R) are correct and (R) is the correct explanation of(A).

B

If both (A) and (R) are correct, but (R) is not the correct explanation of(A).

C

If(A) is correct, but (R) is incorrect.

D

If both (A) and (R) are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
C
Molar heat of vaporisation of water is more than that of ethanol because of stronger H-bonding in water compared to that in ethanol.
