हिन्दीGiven below are two statements: Statement I: The magnitude of enthalpy of vaporisation depends primarily on the strength of intermolecular forces in the liquid. Statement II: Water has a higher standard enthalpy of vaporisation than acetone because of strong intermolecular hydrogen bonding in water. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 1
Both Statement I and Statement II are correct.
Explanation
Strong hydrogen bonds in water require more energy to break compared to the dipole-dipole interactions in acetone, leading to a higher enthalpy of vaporisation for water. Both statements are correct.
