Detailed explanation-1: -Answer and Explanation: 1) Acetone is a dipolar molecule. Therefore, the dominant intermolecular forces between the acetone molecules are dipole-dipole interactions.

Detailed explanation-2: -There are mainly three types of intermolecular forces present in the Methanol which are Hydrogen bonding, dipole-dipole interaction, and London dispersion interaction. The strongest intermolecular force in the Methanol is Hydrogen bonding.

Detailed explanation-3: -Acetone has the weakest intermolecular forces, so it evaporated most quickly. Water had the strongest intermolecular forces and evaporated most slowly.

Detailed explanation-4: -Methanol and ethanol have similar structures and similar intermolecular forces, but differ in molecular size. Methanol has the higher vapor pressure because its molecules are smaller than those of ethanol, and so its intermolecular forces are less than ethanol’s.
