B. Hexane has stronger intermolecular forces, so it boils at a lower temperature. On a molecular level, the intermolecular forces between the water molecules are decreasing. That's because there is a different kind of intermolecular force present in pentanol: dipole-dipole interacon. C) I- pentanol with another molecule of pentanol intermolecular forcescan sertraline cause burning sensation. It is followed by the ethanol, 1-propanol and 1-butanol. Ethanol is a longer molecule, and the oxygen atom brings with it an extra 8 electrons. (van der Waals force exist in all molecules and is significantly weaker than hydrogen bonds, so it will not be mentioned here) First draw the structure out, and find all possible dipoles. These forces are called intermolecular forces. National Center for Biotechnology Information. 2.6.1 Intermolecular Forces.
