Question

Quizplus · Accepted Answer

The molecule of liquid propanol contains polar covalent bonds due to the electronegativity difference between oxygen and hydrogen atoms. This results in a dipole moment in the molecule. Therefore, dipole-dipole forces are present. Additionally, the molecule contains an -OH functional group that can participate in hydrogen bonding with adjacent molecules. Finally, since propanol is a larger molecule, London dispersion forces are also present between the molecules. Therefore, all three types of intermolecular forces, including dispersion, hydrogen bonding, and dipole-dipole forces, are present in liquid propanol.
