Question

Statement 1: Molar entropy of vaporization of water is different from ethanol.
Statement 2: Water is more polar than ethanol.

• A. If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation of the statement 1
• B. If both Statement 1 and Statement 2 are true but statement 2 is not the correct explanation o f the statement 1
• C. If Statement 1 is true but Statement 2 is false
• D. If Statement 1 is false but Statement 2 is true

Answer 1

Answer: (B)

The molar entropy of vaporization of water is different from ethanol due to hydrogen bonding.According to $VSEPR$ theory water molecule has two lone pairs of electronsand has angular shape and show some polarity which is higher than that of ethanol.So both statement 1 and statement 2 are correct but statement 2 is not the explanation of statement 1
