Question

Heat of vaporization at the boiling point: water - 539 cal/g; alcohol - 204 cal/g; chloroform - 59 cag/g what probably causes chloroform to have the lowest heat of vaporization?

Answer 1

Due to chloroform has the lowest intermolecular forces among these molecules because both alcohol and water have hydrogen bonding as intermolecular forces while in case of chloroform only dipole-dipole interaction present which is weaker than hydrogen bonding
So chloroform has the lowest heat of vaporization
